1. A straining, stretching, or bending; the state of being strained; as, the intension of a musical string.
2. Increase of power or energy of any quality or thing; intenseness; fervency. Jer. Taylor.

3. (Logic & Metaph.) The collective attributes, qualities, or marks that make up a complex general notion; the comprehension, content, or connotation; -- opposed to extension, extent, or sphere.
This law is, that the intension of our knowledge is in the inverse ratio of its extension. Sir W. Hamilton.
In linguistics, logic, philosophy, and other fields, an intension is any property or quality connoted by a word, phrase or other symbol. In the case of a word, it is often implied by the word's definition. The term may also refer to all such intensions collectively, although the term comprehension is technically more correct for this.
The meaning of a word can be thought of as the bond between the idea or thing the word refers to and the word itself. Swiss linguist Ferdinand de Saussure contrasts three concepts:
Intension is analogous to the signified, extension to the referent. The intension thus links the signifier to the sign's extension. Without intension of some sort, words can have no meaning.
Intension and intensionality (the state of having intension) should not be confused with intention and intentionality, which are pronounced the same and occasionally arise in the same philosophical context. Where this happens, the letter s or t is sometimes italicized to emphasize the distinction.

Lettris is a curious tetris-clone game where all the bricks have the same square shape but different content. Each square carries a letter. To make squares disappear and save space for other squares you have to assemble English words (left, right, up, down) from the falling squares.
Boggle gives you 3 minutes to find as many words (3 letters or more) as you can in a grid of 16 letters. You can also try the grid of 16 letters. Letters must be adjacent and longer words score better. See if you can get into the grid Hall of Fame !
