If "το" is the neuter definite article, then why is it used before "boy" or am I miss applying the rule.
Το αγόρι is grammatically neuter gender, although it is a male. It's a Greek irregularity.
Same thing happens with το κορίτσι = the girl and το παιδί = the child.
It's not an irregularity. Grammatical gender has nothing to do with biological sex.
Thanks, I guess I'll have to pay attention to remember exceptions.
On a previous exercise "I have the winter caps" was translated to "Εγώ έχο τους σκούφους", being that "winter caps" is "οι σκούφοι"
The question is, are the nominative and accusative forms of "το γάντι" spelled the same?
Yes, it's the same for all neuter nouns.
