Determining gender of words ending in “e”

Question

When learning Spanish, there are basic rules taught about word gender: words ending in o are usually masculine, words ending in a are usually feminine.

What about words ending in e? Are there any guidelines or rules of thumb for determining the gender of these words? Are the majority of words ending in e masculine or feminine?

Answer 1

Son masculinos terminados en -e:

• Nouns ending in -aje (sustantivos terminados en –aje): el coraje
• Colors (colores): el verde
• Numbers (números): el catorce
• Rivers (ríos): el Contramaestre
• Seas and lakes (mares y lagos): el Caribe

Answer 2

I think most words ending in -e are femenine. For example:

• La clase
• La torre
• La gente
• La sangre

However, there are a lot more exceptions for words ending in -e than for words ending in -o. For example:

• El hombre
• El equipaje
• El pie

Answer 3

I read that in general:

• the words ending in aje are masculine
• the words ending in ie are feminine

There are words with both genders, and the meanings are different depending on the gender, e.g. arte, corte, frente.
There are words with both genders, and the meanings are the same for each gender, e.g. casete, interrogante.
