Verbs do not flex for gender, but for grammatical person. Necesito always means "I need", and necesita means "he/she needs".
Necesito = I need
Verbs are conjugated to agree with the subject.
They do not have gender and do not agree with nouns.
necesitar (to need)
(Yo) Necesito = I need
(Tú) necesitas = you (familiar) need
(Usted, él, ella) necesita = you (formal), he, she needs
(Nosotros) necesitamos = we need
(Ustedes, ellos, ellas) necesitan = You (plural), they (male or mixed), they (female) need
If "phone" wasn't accepted, please use the button to report the oversight. The course creators don't read every comment to every sentence discussion, but they do get the reports. Thanks!
My answer was correct minus a typo-- other times this is ok and other times it is not. Why? It is frustrating and often due to the phone keyboards
If you make a typo that spells out another valid word in the target language, it gets marked as an error. For example, if you want to type "live" but you say "love" instead, it's counted wrong. If you mistype it to "luve", it will be graded as a simple typo.
