Put the last of the lager into a new stein (6)
I believe the answer is:
insert
'put' is the definition.
The definition and answer can be both to do with communicating as well as being verbs in their base form.
Maybe you can see a link between them that I don't see?
'last of the lager into a new stein' is the wordplay.
'last of' says to take the final letters.
'into' is an insertion indicator.
'a new' is an anagram indicator.
The last letter of 'lager' is 'r'.
'stein' anagrammed gives 'inset'.
'r' placed into 'inset' is 'INSERT'.
'the' is the link.
Can you help me to learn more?
(Other definitions for insert that I've seen before include "Put something inside something else" , "One might be seen" , "Place (something) inside (something else)" , "supplement" , "Put thing in between others" .)
