Few words I have been learning every day few words since few weeks so i'm going to describe those words along with examples, 1.Collaborate = work together We have to collaborate on our project. 2.Ambiguous = not clear What he has seen in that video that's ambiguous. 3.Resilient = easily recover from difficult situations She could be resilient from her past. 4.Retrospect = looking in the past mistake There is no use by virtue of retrospect because of you can't change past things. 5.Optimum = best If we do our best we will get optimum result. if you know any new words you can post here that would help me a lot, thank you all. Have a great day!
