I saw an example sentence of the usage of word "lack" and it triggered another question in my mind.
The sentence is that
The teacher was lacking in communication skill
but what if I say
The teacher was lacking communication skill
Because dictionaries say that word is used like "<someone> lacks <something>"
So my questions are:
- Is my sentence grammatically correct?
- Does my sentence have the same meaning?
- When should I use the form "lack in"?
