a whole string of gaffs
I’ve seen this mistake several times lately, which is to say I’m not calling you out specifically. Anyway…
While the word did intitially indicate something verbal, the usage has grown to include other kinds of blunders. My usage is in keeping with the current Webster Dictionary definition which makes no mention of anything verbal and instead indicates that it applies to blunders and mistakes - exactly how I would characterize what JJ Abrams body of work is full of.
