His conversation does not show the minute hand; but he strikes the hour very correctly. [ Samuel Johnson ]

Portion or Part? The distinction between these words is usually unheeded. A portion is a part assigned, allotted, or set aside for a special purpose; part has a less limited meaning. Hence, we may say correctly:
In what part of the city do you live?
What portion of the estate do you inherit?. [ Pure English, Hackett And Girvin, 1884 ]

Occur or Transpire? The misuse of these words is very common. Occur means simply to take place, to happen; transpire to leak out, to come to light. Hence, it is incorrect to say, The annual school exhibition transpired last week. The proper word here is occurred. But transpire is correctly used in such a sentence as, The proceedings of the caucus have not yet transpired. [ Pure English, Hackett And Girvin, 1884 ]
