Common Word Mistakes: A LOT, ALL RIGHT, ALL TOGETHER

A lot (two words) is an informal phrase meaning "many." It can take an adjective, for example, "a sizeable lot."

Example: Karl needed a lot of time for the job.

Allot means "to distribute between or among." It has the same root as lottery.

Example: He allotted three breaks a day to everyone in the department.

Alot does not exist as a word.


Alright is a nonstandard abbreviation.

Spelling all right as two words is all right. 


All Together or Altogether ?

All together means "together in a single group."

Altogether means "completely" or "in all."

Examples: We were able to walk all together.
There were ten of us altogether, counting Mr. Bemis.
He was altogether baffled by the question.
