Omit needless words.
The artificial language Toki Pona based on Taoist philosophy of the virtue of simple thought, life, and communication. It takes this to pretty extreme levels - for example, "pona", the word for "good", is intentionally designed to also mean "simple", and "ike" for "bad" or "evil" intentionally also means "complicated".
Guy Steele once gave a talk on computer language design, "Growing A Language", in which he restricted himself to using English words of one syllable, and allowed himself to use longer words only when he defined them first.
