The lady had a "smell" on her face
There are just so many words in the English language that present a challenge for those learning, those for whom English is a second or third language.
I've been teaching in China on and off for three years - and have many stories to tell and enjoyed reading the post Commonly Misused English Words.
There are two pairs of words that have occurred frequently in my class room that always make me want to laugh. I do laugh, but not at the students in the classroom.
The first is smell/smile - "The lady had a smell on her face." Clearly the student meant "smile" and it came in homework so I was able to laugh out loud without embarrassing the student. I have learned that it is a common one.
The other one is snacks/snakes - "The students ate some snakes." Clearly the student meant "snacks". Again it was in homework.
But all around in China you see/read confusing signs and "Chinglish." Many problems arise from the online translator - which is why one also sees many errors and hilarious items on a menu in China.
Still it makes for many opportunities in China for English teachers.
