Vague quantifiers
• “Always” almost always means always• “Never” almost always means never• Any other vague quantifier is . . . vague• Vague quantifiers convey relative position only• Meaning varies from one person to another• Meaning varies from one question to another• Grammatical opposites aren’t perceived equally
“Sometimes”
• “asking questions in class” 2 times per week• “working with other students outside of class” 1 time per month• “making a class presentation” 2 times per
semester• “participating in a community-based project” 1 time per year
How Often is Often Revisited: the Meaning and Linearity of Vague Quantifiers Used on the National Survey of Student Engagement -- Laird, et al., Indiana University, 2008
Vague quantifiers of behavioral frequency, Marincic, 2011
“Stay away from using words like “often,” “usually,” “generally,” etc. Each person’s thought process is different and some people may infer a different meaning.”

Quotes from focus groups, Purdue, 2012-2013
“I feel like here in the US people use stronger
language, like ‘Oh, this is so wonderful.’ But for me,
I’m not so willing to say it.”
“Americans use a lot of hyperbole: ‘It’s super, it’s
wonderful!’ That is not language we use where
I come from.”
