How to say removing redundancy and/or duplicate entries from a list of items with a single word?

  • Is this a programming question? short_list = unique(long_list); is the normal idiom. – tchrist Apr 4 '13 at 17:44
  • No, it's not a programming question. – qazwsx Apr 4 '13 at 18:05

    That's too bad because uniquifying is good and proper programming slang for the process: en.wiktionary.org/wiki/uniquify – Wayfaring Stranger Apr 4 '13 at 18:40

"Pruning" a list or database is an expression I've heard several times.

    "Pruning" doesn't necessarily imply removing duplicates; it could also be used to describe, for example, removing old entries from a database. – Wooble Apr 4 '13 at 18:18
  • True! It describes removing any unwanted stuff, not necessarily duplications. On the other hand, if my job involved going through a list or database and eliminating duplicates, I'd describe it as pruning. We're getting down to context, really. – Roberta Davies Apr 4 '13 at 18:58
