Hi All,
I'm new here and I'm sure I'll be using this forum a great deal in the near and distant future.
I'm starting a TESOL course in Jan and working through an assignment raising my awareness of grammar etc...

I'm a bit stuck on one particular question relating roughly to lexical awareness.

"Factors such as (in)formality, countabilty and multiple meanings may influence the difficulty of learning a new vocabulary item. What problems might you anticipate with the following words?

1) Radio
2) Astonished
3) Pecuniary

Can anyone give me a hand? I've tried researching all three but haven't got anywhere.

Many thanks,

Vicky
