Strange language from criminal in gaol (5)
I believe the answer is:
lingo
This could be a double definition.
'strange language' is the first definition.
(I've seen this before)
'criminal in gaol' is the second definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'from' is the link.
Can you help me to learn more?
(Other definitions for lingo that I've seen before include "Jargon, language (colloq.)" , "means to communicate" , "Foreign language or dialect: jargon" , "Language (informally)" , "Vernacular" .)
