Two words or signs with different meanings that differ in exactly one sound or sign parameter.
In precise terms
A pair of forms in the same language that occur in the same environment and differ in only one phonological element, with a difference in meaning. That contrast is evidence that the differing elements belong to separate phonemes in that language.
An example
pill /pɪl/ vs kill /kɪl/
What is going on here
The words are identical except for the first sound, and changing /p/ to /k/ changes the meaning. That makes them a minimal pair and shows that /p/ and /k/ contrast as separate English phonemes.
Why this matters when you are learning a language
Minimal pairs turn pronunciation practice into a precise listening and speaking task. They show which sound differences can change meaning in the language you are learning, so you can prioritise contrasts instead of trying to imitate every phonetic detail at once.
Across languages
A useful minimal pair is language-specific: two sounds may distinguish words in one language but be allophones in another. Signed languages have minimal pairs too, differing in one parameter such as handshape, location, movement or orientation while keeping the others the same.
