“The man walked to the post-once only to-day.” Yesterday he rode and the day before he drove. Today is the only day that he walked.
George Eliot, in Middlemarch, says: “I only know two gentlemen who sing at all well,” and in another place, “I have only seen her once before.” The word only should be placed before two in the first sentence, and before once in the second.
Onto
There is a growing tendency to write the words on and to as one word. “Although nearly drowned he yet had strength enough to climb onto the rock.” The use of upon or on is generally better. When neither of these can be used write on and to as separate words.
Outstart
This word is sometimes used when outset should be employed.
Over and Above
“He earned twenty dollars over and above his expenses.” Use more than or above.
“Is she the party of whom you spoke?” “No; she is the person.”
