are lanche and leite similar in sound? I couldn't tell them apart when listening to the computer voice. :(
They both start with an l and end with a che sound, but the middle is different. Lanche has an ahn sound and leite has an ay sound.
Bom for masculine, boa for feminine. ( Dia is tricky, because it is masculine)
bom - masculine and boa - feminine we have to use according to the objects gender.
Bom is when the word's gender is masculine and boa when is feminine
Yes, you are correct.
Some words with 'CH': cheio; chamego; chamar; chifre; chofer; achar; machucar; salsicha.
These words have the 'SH' sound as in: sheep; shark; shell; shoe; shelf; shirt.
