For and since in English grammar are two prepositions that help you talk about time. Many students get confused between for and since because both are used to show how long something has been happening. To show the duration or length of time, you should use for in a sentence like "for two hours" or "for five years". It tells you how long something has continued. On the other hand, use since in a sentence when you need to show the starting point of time, like “since Monday” or “since 2010”. It tells us when something began.
Learning the difference between for and since is important because it helps you make correct sentences in English tenses, especially in the present perfect and past perfect tenses. Knowing how to use for in a sentence and how to use since in a sentence can also make your writing and speaking sound natural and clear.

Before learning how to use for and since, it’s important to understand the meaning of for vs since. Both are prepositions of time, but they are used differently in grammar. Check the for vs since meaning here:
For is used to show how long something has been happening. It tells the duration or period of time. For example, I will be on vacation for a month.
Here, it means the action continues for one month.
Apart from time, for can also show the purpose of an action, like 'This gift is for you.'
In grammar, “for” mainly works as a preposition, but sometimes it can also act as a conjunction.
For is pronounced as /fɔːr/ in British English and /fɔr/ in American English.
Since is used to show the starting point of time when an action began and continues till now. For example, she has changed a lot since childhood.
It can also mean ‘because’ when used as a conjunction, such as ‘Since it’s raining, we must postpone the picnic.
In English grammar, “since” works both as a preposition and a conjunction. It is pronounced as /sɪns/ in both British and American English.
