Directly, Immediately, As soon as
A faulty English use of the above words has found some favor in the United States. “Directly the whistle blew the workmen left the shop.” Say “As soon as the whistle blew,” etc. “Immediately he closed his speech his opponent rose to reply.” Say “When” or “As soon as he closed his speech,” etc.
Directly denotes without any delay; immediately implies without any interposition of other occupation.
Agreeably disappointed
When our hopes are blasted, our plans balked, our expectations defeated, our intentions thwarted, we are disappointed. We prefer the agreeable to the disagreeable, and plan and labor to secure it. When our plans fail we are disappointed, but not agreeably disappointed. If the new conditions, which are not of our seeking, prove agreeable, it is only after the sense of disappointment has vanished.
Allude to, Refer to, Mention
The word allude is often incorrectly used. Allusion is the by-play of language. It means to hint at by remote suggestions, to speak of figuratively or sportively.
Whatever is directly mentioned, or spoken of, or described, cannot be said to be alluded to. The terms differ in degree, the first being the weakest. An allusion is an indirect reference.
Among the rest
“Mary sat on the beach among the rest.” Say “with the rest.”
