I learned new word-“off beam “from the Chapter 15 Of “The Third Ear” recently .

Original sentence：
Somewhere in the middle I said something that was clearly off beam.

“ off beam “ means
“ wrong “

I try to practice making up sentences :
1. His judgement was clearly off beam.
2. We are off beam in our search for the cues.
3. The informations on the social networking site,some of which are right and some of which are slightly off beam.
