Spelling
For measurements, the comma takes the place of the decimal point, and the period is used to separate the thousands.

Stress
The stress is usually placed on the vowel preceding the last consonant.

Articles
The article is invariable, it is never inflected by gender or number.

Nouns
Nouns have no grammatical gender. Nouns ending in a vowel form their plural by adding -s, and those ending in a consonant add -es.

Adjectives
Adjectives are invariable and do not agree with the noun or pronoun to which they refer. The adjective can precede or follow the noun it describes.

Adverbs
Adverbs are formed from adjectives by adding -ly.

Regular Verbs
With the exception of auxiliary verbs, verbs are not conjugated by person and use the same form invariably, therefore it is mandatory that the subject pronoun is not omitted. The imperative and the impersonal forms (infinitive and participle) must obligatorily omit the subject pronoun.

Irregular Verbs
Some verbs have irregular forms for stems in the past simple and past participle.
