I never came across a 'Gerund' until now, no Idea there was a word for such a thing...astounding....I never came across a gerund until I learned Danish - despite having learned English at grammar school.
How is your Danish now G-CPTN?....I tried to teach myself some a few years back when visiting CPH., and whilst everyone speaks English, my attempts at Danish were very well received indeed!....I enjoyed learning as much as I could...very interesting.
But I could hardly call myself fluent at all! ... especially there as there is, like in Australian English to abbreviate words so much...
