Macroeconomics
1) The field of economics that studies the behavior of the aggregate economy. Macroeconomics examines economy-wide phenomena such as changes in unemployment, national income, rate of growth, gross domestic product, inflation and price levels. (Investopedia.com)

2) The branch of economics that studies economic aggregates (grand totals) e.g. the overall level of prices, output and employment in the economy. (Economics John Slowman)

3) The study of economy-wide phenomena, including inflation, unemployment and economic growth. (Economics N. Gregory Mankiw, Mark P. Taylor)

4) The branch of economics  dealing with the broad and general aspects of an economy, as the relationship between the incomeand investments of a country as a whole. (Dictionary.com)


The study of aggregate economies, including inflation, unemployment and economic growth. 

Unemployment-
1) Unemployment occurs when a person who is actively searching for employment is unable to find work. Unemployment is often used as a measure of the health of the economy. The most frequently cited measure of unemployment is the unemployment rate. This is the number of unemployed persons divided by the number of people in the labor force. (Investopedia.com)

2) The number of people who are actively looking for work but are currently without a job. (note: that there is much debate as to who should officially be counted as unemployed) (Economics John Slowman)

3) Those without a job but who are seeking work at current wage rates. (AQA Economics)

4) Total number of able men and women of working age seeking paid work. Unemployment statistics vary according to how unemployment is defined and who is deemed to be part of the workforce. Traditional methods for collecting unemployment data are based, typically, on sampling or the number of unemployment benefit requests.International labor organization (ILO) computes unemployment on the basis of number of people who have looked for employment in the last four weeks and are available to start work within two weeks, plus those who are waiting to start working in a job already obtained. (Businessdictionary.com)


Generally displayed in percent of population, the amount of people who are without a job at a certain time and are seeking one. 

Inflation-
1) The rate at which the general level of prices for goods and services is rising, and, subsequently, purchasing power is falling. Central banks attempt to stop severe inflation, along with severe deflation, in an attempt to keep the excessive growth of prices to a minimum. (Investopedia.com)


2) is a continual increase in prices throughout a nation's economy. The rate of inflation is determined by changes in the price level, an average of all prices. If some prices rise and others fall, the price level may not change. Therefore, inflation occurs only if most major prices go up. (World Book)

3) An increase in the overall level of prices in the economy (Economics N. Gregory Mankiw, Mark P. Taylor)

4) A persistent increase in the level of prices. (AQA Economics)

It includes all of private and public consumption, government outlays, investments and exports less imports that occur within a defined territory. The value of output (or fincome or expenditure) in terms of the prices actually paid. GDP = GVA + taxes on products – subsidies on products. 
GDP = C + G + I + NX

where:

"C" is equal to all private consumption, or consumer spending, in a nation's economy
"G" is the sum of government spending
"I" is the sum of all the country's businesses spending on capital
"NX" is the nation's total net exports, calculated as total exports minus total imports. (NX = Exports - Imports)

Recession-
1) A significant decline in activity across the economy, lasting longer than a few months. It is visible in industrial production, employment, real income and wholesale-retail trade. The technical indicator of a recession is two consecutive quarters of negative economic growth as measured by a country's gross domestic product (GDP); although the National Bureau of Economic Research (NBER) does not necessarily need to see this occur to call a recession. 
(Investopedia.com)

2) A period where national output falls for six months or more. (Economics John Slowman)

Investment-
1) An asset or item that is purchased with the hope that it will generate income or appreciate in the future. In an economic sense, an investment is the purchase of goods that are not consumed today but are used in the future to create wealth.

Output gap-
1) An economic measure of the difference between the actual output of an economy and the output it could achieve when it is most efficient, or at full capacity. There are two types of output gaps: positive and negative. A positive output gap occurs when actual output is more than the full-capacity output. Negative output gap occurs when actual output is less than full-capacity output.
(Investopedia.com)

2) The difference between actual and potential output. When actual output exceeds potential output, the gap is positive. When actual output is less than potential output, the gap is negative. (Economics John Slowman)

3) The difference between the actual output (such as GDP) of an economy and the output that the economy would be at under full capacity or maximum efficiency (the potential output) A negative output gap, in which actual production is lower than efficient production, indicates that resources are not properly allocated. A positive output gap indicates that GDP is higher than what we can supported by existing labor and capital resources, and is a leading indicator of inflation. (Businessdictionary.com)


4) The output gap is a measure of the difference between actual output (Y) and potential output (Yf).

The output gap = Y- Yf

Negative Output Gap. This occurs when actual output is less than potential output gap. This is also called a deflationary (or recessionary) gap. In this situation the economy is producing less than potential. There will be unemployment, low growth and / or a fall in output. A negative output gap will typically cause low inflation or even deflation.

Positive Output Gap. This occurs when actual output is greater than potential output. This will occur when economic growth is above the long run trend rate (e.g. during an economic boom). It will involve firms asking workers to overtime.

With a positive output gap, there will be inflationary pressures. It will also tend to cause a bigger current account deficit as consumers buy more imports due to domestic supply constraints.
The difference between the trend output of a country (predicted output) and the actual output of a country. There can be a negative or positive output gap. 

Aggregate Supply-
1)The total supply of goods and services produced within an economy at a given overall price level in a given time period. It is represented by the aggregate-supply curve, which describes the relationship between price levels and the quantity of output that firms are willing to provide. Normally, there is a positive relationship between aggregate supply and the price level. Rising prices are usually signals for businesses to expand production to meet a higher level of aggregate demand.  
Also known as "total output".

4) The total demand for goods and services from all sources in the economy. It includes consumer spending, investment by firms in plant, machinery and stocks, government spending, the net effect of international trade. An increase in aggregate demand may lead to an increase in output provided there is underutilized productive capacity in the economy. If there is no spare capacity, and the economy is producing using all available, suitable resources, rising demand is likely to lead to inflation. (MANU'S thoughts) 


The total demand for goods and services from all sources in the economy at a certain price level and in a given time period. Can be calculated using the formula C + I + G + (X - M) 
Deflation
1) A general decline in prices, often caused by a reduction in the supply of money or credit. Deflation can be caused also by a decrease in government, personal or investment spending. the opposite of inflation, deflation has the side effect of increased unemployment since there is a lower level of demand in the economy, which can lead to an economic depression.
