equivocate

Word: equivocate

Meaning: to use ambiguous or unclear expressions, usually to avoid commitment or in order to mislead; prevaricate or hedge

Not the meaning: equate [While writing this post I learned that I've been using equate and equivocate interchangeably. Bad mistake.]

Potential future use of the word: When asked for how long she expected to continue with her blog-writing habit, she equivocated, "Oh, I expect this will last at least a devil's fortnight."

Further notes: Devil's fortnight is a phrase my husband made up to avoid committing to a time frame.
