    Can you give us a context and an example sentence of how the potential word may be used? Also, what research have your done? fool-proof? dependable? reliable? – Hank Jun 22 '17 at 17:39

Old faithful -- Collins

(noun) You can refer to something that has been used or has existed for a long time as an old faithful, especially when it is something you can rely on.

  • Just a heads-up, people have been hit with down votes before for having the temerity to answer requests for a single word with multiple-word expressions... – oerkelens Jun 22 '17 at 17:50
  • Old faithful is an Americanism, and may not make sense to English speakers outside the US. – Jim MacKenzie Jun 22 '17 at 18:14
  • @oerkelens True, that. Thanks for the heads-up. My reasoning is, single words would simply be synonyms of reliable. So, I provided something extra. – NVZ Jun 22 '17 at 19:39
