Help! Dd was reading her reading scheme book to me last night (think it was a fireflies one), it contained the sentence "The removal men begun unloading the lorry". Dd read this as "The removal men began unloading the lorry". I didn't correct her as actually I'm not sure "begun" is correct anyway, and I was more impressed she automatically corrected the grammar rather than reading the word actually written.
I have now spent the day with begun and began fighting it out in my head. Which do you think it should be please?!
