However, conseed is not a common word. It is an archaic form of the verb "to sow" (as in planting seeds).
It's important to note that while concede and conseed sound the same, they have very different meanings.
* Concede means to admit defeat or the truth of something reluctantly.
* Conseed means to plant or sow seeds.
Therefore, in most cases, you will likely be looking for a synonym of concede rather than a homophone.
