"Αυτός πιθανώς είναι ένας ελέφαντας."

[gomarinado]

sorry, I just have to comment. Some examples are so funny. What can be possibly confused with elephant? a mammoth? are we talking time travel situation here? :)

[mica685337]

Maybe a footprint in the ground, it could be an elephants print or a barrel for example. I agree some of the examples are just plain stupid...

[AnCatDubh]

There was a scene on the Israeli version of The Office where the equivalent of Dwayne talked about how the religious woman working there has been pregnant for an unusually long time... so she is probably secretly an elephant.

Not quite sure what could be argued in case of a man―oh.

So... in English it's not exactly ungrammatical but it is awkward to say this. A more likely phrasing is "Possibly it's an elephant." This is rejected as wrong.

[Dimitra956826]

I don't think it's ungrammatical, but I don't think it's awkward either. However, your suggested translation is a valid one. It has been added as an alternative.

[DelynVeaud]

Yes, thats what I wrote...as you say rejected

[Max139317]

I think what would sound more "English" would be the phrase "He might be an elephant." As "might" is frequently colloquially used to replace "possibly".

[jaye16]

"might" has been added as a correct answer.

[Solinje]

How can you not be sure if something's an elephant??

[Sanna689159]

I wrote He is perhaps an elephant and it was considered wrong. Why?

[G.Georgopoulos]

I think it's better to put "perhaps" at the beginning of the sentence - that's the more common thing, at least. But one can't really say "He is perhaps an elephant", because one can't really call something a "he" or a "she" unless they know what they're looking at. Instead of that, it's better to say "Perhaps it is/this is/that is an elephant". If it's indeed an elephant, then you can use the pronouns "he/she", depending on the animal's gender.

Please look at Oxford dictionary

It could be something else. Perhaps
