I imagine that this happen to every language.That's the same here with tree / trees. Both forms exist. Odd how we deem some things to sound more correct than others with no clear reason.
"The last weekend I went fishing and caught three fishes"
She laughed and said: we don't say "fishes", just fish.
The next day I told her:
- I've got a doubt: How about "he fishes three fish?" Is that "fishes" correct?
- Yes, it's correct in that case. It's curious, isn't it?- she said.
Fish or fishes
Though often used interchangeably, these words actually mean different things. Fish is used either as singular noun or to describe a group of specimens from a single species. Fishes describes a group containing more than one species.[58] Hence, as plurals, these words could be used thus:
ツ?。my aquarium contains three different fishes: guppies, platies, and swordtails.
ツ?。The North Atlantic stock of Gadus morhua is estimated to contain several million fish.
We do say "fishes" when we are talking about species/groups of "fish".
Oh, I see.
I think over here most of it is regional, for instance some Irish and Scottish will pluralise sheep, but around here people would get very confused.
lol i can relate! in speech/in context i rarely have to think but id do sh*t-all if someone quizzed me on grammer and rules! guess listening to stuff around you helps... read or keep listening to the radio or something.... it is boring though!born and raised in the US...comes to spelling and grammar, common sense often does not work and you just have to memorize a bunch of rules,
