What is Homophone for cell?

There is no perfect homophone for "cell" in the sense of a small compartment, as in a honeycomb or a prison cell.

However, depending on the context, you could consider:

* "sell" if you are talking about a cellular phone.

* "sel" (an archaic form of "sell") could be used in some very specific historical contexts.

It is important to be aware that these are not true homophones, as they are not pronounced identically.
