Very small or tiny; minute in size. Can also be used as an informal noun referring to a small amount or a young teenager.
A diminutive form of 'tiny,' with the '-ie' suffix adding emphasis to smallness. This pattern of reduplication for emphasis appears in many English words expressing small size, dating to the 18th century.
The word 'teenie' demonstrates how English creates emphasis through sound patterns - the long 'ee' sound somehow feels even smaller than 'tiny.' It's often paired with 'weenie' not just for rhyme but because both words use similar sound symbolism to suggest smallness.
