In Tamil, there is a single word எண்(eN) which means 'count', 'number', 'think'. I am wondering if this is unique to Tamil? I am wondering if the other old classical languages have a similar word.
This is the case for Russian.
The word считать
[ɕːɪˈtatʲ] has two meanings:
- to count as in "I counted my cats; fifteen are they";
- to consider, to think as in "I think that I'm too fat".
The etymology dictionaries (Vasmer) provide with the following explanation (note the Old Indic origin):
< Old Indic
сḗtаti«to comply, think, discover, understand»,
kḗtas«thought, idea, will»,
