There are several ways to name a (.) punctuation mark. I can't understand if they anyhow differ?

  • Period
  • Full stop (also Fullstop)
  • Stop
  • Point
  • Full point
  • Dot

I only use the word "period".

  • The identical symbol may have different names in different contexts. The "⋅" character might be an interpunct in Latin text but would be a dot operator in vector mathematics. A "$" in Canada represents a dollar value, but in Uruguay a peso value. So it is that you do not separate the components of an IP address with periods, and you do not end sentences in prose with points, and you do not indicate a decimal fraction with dot. I would encourage you to check basic references before posting; Wikipedia is usually adequate for initial research.

  • @choster Yeh, I know. But somewhere they say full stop or stop instead of period and sometimes people say dot instead of point. i.e. You should place a full stop before that word and separate the sentence into two. or An examiner says: Her eyes were green [period] She had a beautiful smile [period].

When used to mark the end of a sentence or an abbrevation, period is the common term in the US and Canada. The rest of the English-speaking world (UK, Australia, New Zealand, South Africa, etc.) prefers full stop. Full point is an archaic synonym of these, but no longer used anywhere.

When it is used with numbers, point is used, e.g. 3.6 is pronounced "three point six". Dot tends to be used when giving the name of a website, e.g. "amazon dot com".
