Authoritative Interlingua Grammar Points

 So, these are the list of authoritative Interlingua Grammar points. This one is from IALA. The grammar is the simple one and close to English. The link will be updated eventually.

The Outline or Summary:

1. The Verbs are not conjugated based on the Subjects. Conjugation only happens based on the tenses. Hence, the Subjects may not be omitted and carry the information.

2) Nouns do not have any genders. But, the ending O/A/E or consonants are spread all around without carrying gender conotation. Only living beings can have masculine/feminine genders based the sexes and expressed by O/A ending.

3. Articles and Adjectives do not inflect based on nominal genders or plurality.

4. Imperative and Subjunctive forms are exactly the same. Even the same with the Present tense. Only Sia is the Subjunctive form of to Be.

5. Participles are used as adjectives like in English.

6. Infinitives are used as to verb and nominal gerund (action and activity).
