Questions & Answers about Su casa es grande también.

Why is su used instead of sus in this sentence?

In Spanish, su is used when referring to a single possession (for example, one house). Sus would be used if the person owned more than one house (plural). Since the sentence talks about just one house, su is correct.

How do I know if su is referring to his, her, or your?

In Spanish, su can mean his, her, their, or your (formal). You can usually figure out the meaning from context. If you’re on formal terms with someone, su can mean your, while if you’re talking about a third person whose gender is not specified, it can refer to his, her, or their.

Why is es used instead of está?

Spanish has two verbs for “to be”: ser and estar. Generally, ser is used to describe permanent, inherent characteristics (like size or color), and estar is for temporary states or locations. Here, es (from ser) is used because having a “big house” is considered a characteristic, not a temporary condition.

Can I place también elsewhere in the sentence?

Yes. In Spanish, también is flexible. You could say Su casa también es grande or También es grande su casa. The meaning stays the same, but the emphasis changes slightly.

Why is casa feminine, and do I have to change grande to match feminine nouns?

Words in Spanish have grammatical gender, and casa is feminine by convention. The adjective grande has the same form for both masculine and feminine nouns, so you do not change its ending. If the adjective were something like bonito/bonita (“pretty”), you would need to adjust the ending to match the gender.

Is there a difference if I say gran instead of grande?

Yes. Gran is a shortened form of grande placed before a singular noun to add a sense of importance or distinction (for example, una gran casa = “a great house”). When it comes after the noun, as in casa grande, it literally means “big.” In the sentence you have, grande naturally suggests size.
