Questions & Answers about Haec ianua firmior est quam illa.
Because ianua is a feminine noun in Latin.
The demonstrative meaning this has to agree with the noun it describes in:
- gender
- number
- case
So with a feminine singular nominative noun like ianua, the correct form is haec.
A quick comparison:
- hic = this, masculine singular nominative
- haec = this, feminine singular nominative
- hoc = this, neuter singular nominative/accusative
So haec ianua means this door.
Both haec and ianua are in the nominative singular.
That is because haec ianua is the subject of the sentence: it is the thing being described as stronger.
Breakdown:
- haec = nominative singular feminine
- ianua = nominative singular feminine
- firmior est = is stronger
So literally the structure is:
- This door = subject
- is stronger = predicate
