  The extension of meaning, the opposite of restriction, means the widening of a word's sense until it covers much more than what it originally conveyed.

2)Narrowing

  Narrowing of meaning, also called restriction of meaning, means that a word of wide meaning acquires a narrower, specialised sense which is applicable to only one of the objects it previously denoted.

3)Elevation

  When the meaning of a word narrows toward a more favourable meaning it is called elevation
