Enter lift, disorderly charge to get in first (10)
I believe the answer is:
infiltrate
'enter lift disorderly charge to get in first' is the definition.
I can't judge whether this defines the answer.
'enter lift disorderly charge to get in' is the wordplay.
'enter' indicates putting letters inside.
'disorderly' is an anagram indicator.
'charge' becomes 'rate' (rate is a kind of charge).
'to get' says to put letters next to each other.
'lift' anagrammed gives '[lift]'.
'[lift]'+'rate'='filtrate'
'filtrate' placed around 'in' is 'INFILTRATE'.
Can you help me to learn more?
(Other definitions for infiltrate that I've seen before include "Worm one's way into" , "Enter undetected" , "enter secretly" , "Sneak into" , "gradually sink in" .)
