Questions & Answers about Sus manazas son fuertes, pero él está cansado.
Why is it manazas with an -a instead of -os when the root word is mano?
Even though mano ends in -o, it is a feminine noun. When you add an augmentative suffix like -azo or -aza, the suffix must match the original noun's gender. Therefore, the feminine mano takes the feminine suffix to become manaza (plural manazas).
Does adding the -aza suffix in manazas just mean his hands are physically large?
It means they are physically large, but suffixes like -azo and -aza often add a subjective feeling too. They can imply clumsiness or rough, heavy power. Here, paired with fuertes (strong), it emphasizes that his hands are impressively large and powerful.
Why does this sentence use both son and está?
Since the sentence refers to one person, why is the first word Sus plural instead of Su?
