I have a maths lesson today.
[aɪ həv ə ˈmæθs ˈlɛsn̩ təˈdeɪ.]
The lesson starts at nine o'clock.
[ðə ˈlɛsn̩ ˈstɑrts ət ˈnaɪn əˈklɑk.]
Was the English lesson interesting?
[wəz ði ˈɪŋɡlɪʃ ˈlɛsn̩ ˈɪntrəstɪŋ?]
"lesson" is in the lesson "Education" (Level 35), along with 10 other useful words. LinDuo has 180 topic lessons like this one, 2,375 words in total.
