• This suffix retains the gender of the root word and usually its final ⟨a⟩ or ⟨o⟩ too, even if the former ends a masculine word or the latter ends a feminine one:^[1][2][3]
  • ‎problema (“problem”) + ‎-inho → ‎probleminha (“little problem”), not *probleminho
  • ‎tribo (“tribe”) + ‎-inho → ‎tribinho (“tribelet”), not *tribinha

This is always true in prescriptive grammar; however, some informal formulations deviate from this pattern, such fotinha, from foto. Brazilian grammarian Evanildo Bechara additionally deems -inha valid if the root is a clipping of a feminine word ending with ⟨a⟩, such motinha from moto, in turn a clipping of motocicleta.^[4]

• The suffixes -inho, -ão and -mente do not alter vowel qualities in the root word:
  • ‎certo (“accurate”) + ‎-inho → ‎certinho (“precisely correct”, with /ɛ/); compare certeiro (with /e/ or /ɨ/)
