Conjunctions
Previous (Adjectives)Index (Grammar)Next (The indefinite articles 'a' and 'an')

When that is used as a conjunction, do not use it again after an interjected clause, however long the sentence may be:

The Director knew that, however great the travel difficulties to be overcome, that his assistant would be there. (Omit the second that.)

Use while only in its true sense of time:

He continued the traverse while I collected samples.

Otherwise, use and or although instead of while, such as in the following sentence:

At the conference the terrain scientist gave a talk on sampling procedures and (not while) the geophysicist spoke on new instrumentation.
Although (not while) we found no evidence of fossils in the field, laboratory analysis revealed an abundant fauna.

Do not use also as a conjunction after and.

The word like can be used as a conjunction in constructions such as He ran like a rabbit, but do not use it in the sense of 'as' or 'as if':

The field assistants worked as if they were possessed.
not The field assistants worked like they were possessed.
