Hello.
This is the kind of question I'd normally ask Her Hon. by PM but I figured it might be of use to others -- or I might just be a lemon, and everyone knows it already. My experience of grammar and tenses was only taught to me in French, never English. I was the first cohort of GCSEs in 1988 and my (grammar!) school (the incredibly gayly-named Bournemouth School for Boys
)chose to combine English into one qualification so we got a grade for Lang and a number for Lit; eg: A3, C4 etc... Consequently I struggle with the rules and names of tenses.
Anyway, my question is re words like swum/swam and sunk/sank.
I'm not sure which one to use and have been going kind of by intuition/sound. I feel like
swam is in the past, but actively 'doing' swimming, and swum is in the past with the swimming having been 'done'. Similarly, sunk would be, say, an item that has already got submerged, whereas sank, is reporting its action of sinking in the past.
Am I right? I've been going from Strunk and White for years, but realised recently that is American English so I have to be careful my WIPs aren't full of US and UK English.
