Difference Between Since and Ago (With Table)

The English language has different terminologies to mention the time factor in the sentences. Of course, the usage of correct tense forms can determine the time, but what do we do while talking about a ‘certain point in time?’

English is classical when it comes to the bifurcation of any aspect. The aspect of time is also dealt with impeccably for every possible instance of time. There are two important instances in time. One is ‘Period’ and the other is ‘Point in Time’. These two make a whole lot of difference in time factor while mentioning it in sentences.

Over a period of time; A year, A month, 10 years, summer, etc. The point in time is specific; One year, 2 days, 30 minutes so and so forth. Indeed, the examples cited in both categories may also feature in either case, depending on the context of the sentence.

The two important words which play a vital role in enunciating ‘point in time’ alone are ‘Since’ and ‘Ago’. They both fall under the same bracket of ‘past’, however, there are many differences between the two.

Since vs Ago

The main difference between Since and Ago is that ‘Since’ denotes something that is still happening till the present, however ‘Ago’ is the word that points out time in the past.
