questionnaires

1. 1
   noun

   Plural of questionnaire.

   The research team mailed thousands of questionnaires to households across the region.

   Incomplete questionnaires were set aside and excluded from the final analysis.

   Note

   One spelling, two jobs: questionnaires is the plural noun, and it is also the verb form, because questionnaire can mean to survey people with such forms. Context tells them apart. A number, an article or an adjective marks the noun, as in thousands of questionnaires or the incomplete questionnaires. A singular subject directly in front of it marks the verb, as in the clinic questionnaires its patients.

2. 2
   verb

   Third-person singular simple present indicative of questionnaire.

   Note

   Behind this form is questionnaire used as a transitive verb, meaning to survey people with questionnaires. Its direct object is the people being surveyed, and the topic follows with about: the firm questionnaires its buyers about pricing. Because the verb needs an object, a sentence like the firm questionnaires weekly sounds unfinished. Add the people surveyed, or switch to surveys.
