Synonym discussion
Sense: verb/2
These four verbs all describe things that are similar or match in some way, but they differ in how much similarity they imply. Overlap is the broadest and most common: it means that two or more things share some features or area but not all of them. Coincide is more formal and can mean either 'happen at the same time' or 'agree exactly'; when used for traits or opinions it often suggests a closer match than overlap does. Correspond suggests a systematic matching relationship — such as one set of data matching another set — and is common in academic or technical contexts. Share is the simplest everyday word and does not distinguish between partial and full commonality. For example, two friends may overlap in taste in music (some favourite bands are the same, others differ), while their political views may coincide more closely on certain issues and correspond to their economic backgrounds.

Etymology
Overlap was formed in English around the 1700s by combining the prefix over- (meaning 'above, across') with the verb lap, which originally meant 'to wrap or fold'. In Old English, lapian meant 'to fold or wrap around', and it is related to the word lap as in 'the part of clothing that can be folded over'. The physical sense — one thing lying partly over another — appeared first. By the late 1800s, the word had developed figurative uses for time periods, interests, and responsibilities that share common ground. The adjective overlapping emerged soon after, staying close to the verb's meaning.
