Widow woman
“And Jeroboam the son of Nebat, an Ephrathite of Zereda, Solomon’s servant, whose mother’s name was Zeruah, a widow woman, even he lifted up his hand against the king.”—I Kings xi, 26.
The expression is now regarded as an archaism, and not to be used in modern speech or writing. Omit woman.
Why
Many persons have a foolish habit of beginning their answer to a question with the word why. In some cases it doubtless has its origin in the desire to gain time while the mind is preparing the answer, but in most instances it is merely a habit.
Some persons prefix the word why to the statement of a fact or to the asking of a question. This is even worse than to employ it to introduce the answer. Restrict it to its legitimate use.
Look at here
This is one of the numerous expressions designed to call the attention of the person addressed to the speaker. It is both ungrammatical and vulgar. The omission of at will render it grammatical. “See here” is still better.
Look and see
“Look and see if the teacher is coming.” The words “look and” are superfluous. “See whether the teacher is coming” is a better expression.
