So numbers don't get the accusative?
... But I have four grandfathers...
(all but one of my grandparents remarried, so I have 7 XD)
avoj means grandfathers or grandparents? Or both?
avoj - grandfathers
avinoj - grandmothers
geavoj - grandparents
And a singular grandparent of unknown or non-binary gender?
geavo. adding the prefix ge- makes anything gender-neutral, as far as I'm aware
Ge- in the plural implies male and female together, but hopefully a more neutral meaning can also be understood.
Singular ge- as a gender neutral is, as far as I'm aware, fairly widely used and understood, but not technically standard.
Meaning can change over time. Just needs more esperantists using ge- that way until its unkversally understood
do you know if it would understood if I said 'gavoj' like, condencing 'geavoj' - it's a habit I have from French.
You need to say ge-avoj, or people will not understand you.
avoj means grandfathers, while geavoj means grandparents (implies male and female together).
Why does avojn end in an n, rather than just being avoj?
-n is the accusative (direct object) noun ending. In the sentence, "avoj" is the direct object (receives the action of the verb "havas") so has to end in -n.
