Position of the Adjective
'Gigantes' usually goes after the thing it describes: 'edificios gigantes' (gigantic buildings). Placing it before the noun ('gigantes edificios') makes the description sound more poetic or emphasizes the quality.
Agreement with Feminine Nouns
Mistake: “Using 'gigantas' when describing feminine nouns (e.g., 'casas gigantas').”
Correction: The adjective form is always 'gigantes' regardless of the gender of the noun it describes: 'casas gigantes' (huge houses). 'Gigantas' is only used as a noun meaning female giants.
