Notoriously thirsty thespian drinking gallons in lake showed up again (2-7)
I believe the answer is:
re-emerged
'notoriously thirsty thespian' is the definition.
The answer and definition are different parts of speech. However, adjectives and past participle verbs can occasionally define each other.
'drinking gallons in lake showed up again' is the wordplay.
'drinking' means one lot of letters goes inside another (inserted letters are consumed or drunk).
'gallons' becomes 'G' (abbreviation).
'in' means one lot of letters goes inside another.
'lake' becomes 'mere' (mere is a kind of lake).
'showed up again' becomes 'reed' (I can't justify this - if you can you should give a lot more credence to this answer).
'g' put inside 'mere' is 'merge'.
'merge' placed into 'reed' is 'RE-EMERGED'.
