I do have a question for those words
is it correct if i say
1) Our teacher gave us a concise lecture .
2) My father likes to elicit the information from me .
3) The student's performence tie in with his family situation and life style.
Are those sentances correct
I wouldn't describe a lecture as concise, I would simply call it short.
Whether you need the article in number 2 depends on the context.
I'm not sure how someone's performance can tie in with their lifestyle but if it can, then the sentence is fine.
