both . . . and
Matching the parts joined by the correlative pair.
After both . . . and, put the same part of speech on each side: a noun with a noun (both the brief and the exhibit), an adjective with an adjective (both clear and brief), a phrase with a phrase (both in draft and in proof). Place both so that what follows it matches what follows and. See also correlative conjunctions and parallelism.
Examples
Use She both drafted the brief and argued it. (Finite verb with finite verb.)
Use both the brief and the exhibit (Noun with noun; the on both sides.)
Avoid both the brief and exhibit (the appears before only one of the paired nouns; many editors treat that as poor form.)
Avoid The memo was both a careful edit and badly organized. (Noun phrase with adjective phrase.)
