Associate with large tattoo (4)
I believe the answer is:
link
'associate' is the definition.
(synonyms)
'with large tattoo' is the wordplay.
'with' says to put letters next to each other.
'large' becomes 'l'.
'tattoo' becomes 'ink' (I am not sure about this - if you are sure you should believe this answer much more).
'l' put next to 'ink' is 'LINK'.
Can you help me to learn more?
(Other definitions for link that I've seen before include "website feature" , "Physically join" , "Connect" , "Connexion" , "Relationship; intertwine" .)
