Last, the superlative form of late (the other one being latest) has been derived from the old English word “latost”. In some situations, we cannot use latest as the superlative degree of late, instead we use last.
For example –
“I reached there late today” – if we want to change to superlative, it would be wrong to say “I reached there latest today”. Rather, it would be more appropriate to say “I was the last person to reach there today.”
For example, last session, last day, last time, last person etc…
· When was the last time we met?
· I was the last person to join.
Last as an adverb means previous (in a way final) –
· When I spoke to her last time, she told me she was not well.
· That was the last I heard of him.
· The session lasted for 3 hours.
· This is a long-lasting solution.
· The least we can do is go home and play (that’s the last option)
Sometimes, we say Last but not least! Here comes the difference between both! Last but not least is referred in situations wherever we are talking about multiple points or persons and the last is as important as first (it is no less than others). This means even though the point is being mentioned in the end, it is as significant as all the others including the first one.
