dear teacher,

if the option is given as 'opted for the priciest item on the menu' then is it right. Is it true that you cant use 'opted' alone.

Hi everybody, I have a question:what means "the priciest item"? I can't find in the dictionary the word "priciest". Why it's not "expensive" instead it.

Thanks in advance,

hope to hear you soon :)

[Mister Micawber]

Priciest = most pricey = most expensive. Look HERE.

When does one use choose and when opt?

[Mister Micawber]

For one thing, 'opt' refers to a set of predetermined choices. For another thing, 'opt' is usually rather formal or a business term.
