"Logarithm" is a word made up by Scottish mathematician John Napier (1550-1617), from the Greek word logos meaning "proportion, ratio or word" and arithmos meaning "number", ... which together makes "ratio-number" !
In its simplest form logarithm gives the info about:
how many a number can give another number
basically its used to get the power ie. the exponent of the base number in the log with respect to the log number
for eg:
1. log2(8)=3 ie 23 = 8
how many a number (to the base number) (2)
another number (log number) (8)
raise to power (3)

2. log2(4)=2 ie 22 = 4
same goes for the negative logarithms:
