Use 'insinuate' when suggesting something negative in a roundabout way without claiming it outright. Are you insinuating that I'm not qualified for this job?
Pro Tip 2/3
Indirectly Pointing
'Insinuate' can show one's reluctance to state something directly, often to avoid confrontation. He didn't say it, but he insinuated that the project might fail.
Pro Tip 3/3
Potentially Offensive
Be cautious, as 'insinuate' can sound accusatory and may offend if the implication is taken negatively. I don't like the way she insinuated that I was to blame.
