I noticed that these tags are very similar and effectively have the same meaning.
I searched in two search engines
define proverb and
define saying, here are the results:
a short pithy saying in general use, stating a general truth or piece of advice.
a short, pithy expression that generally contains advice or wisdom.
a short, well-known pithy saying, stating a general truth or piece of advice.
a short, pithy, commonly known expression which generally offers advice or wisdom.
Going by these obvious similarities, shouldn't they be merged?
If they are to be merged, which should be a synonym of the other?
'Saying' is slightly more popular than 'proverb' (Google Ngrams) but proverb sounds more academic.
