Bad toothache
As it is a rare thing to have a good toothache, we scarcely need the adjective bad to distinguish between the two kinds of toothache. Say severe.
Beautifully, Beautiful
After verbs of seeing, feeling, tasting, and smelling, the adverb is often incorrectly used for the adjective.
“The colonel looked handsomely in his military dress,” “I feel splendidly to-day,” “This peach tastes badly,” “The rose smells sweetly,” are incorrect. Use handsome for handsomely, very well or in good spirits for splendidly, tastes bad or has a disagreeable taste for badly, and sweet for sweetly.
Beg, Beg leave
“I beg to announce the sale of a collection of rare and costly rugs.” “I beg to acknowledge your kindness in sending me this handsome present.” In each case say “I beg leave to,” etc.
Due, Owing
His success was due to his honesty and energy.” That is due which should be paid as a debt; that is owing which is referred to as a cause or source.
“The bill is now due and payable at the gas office.” “His success was owing to his honesty and energy.”
