Functional load

In linguistics and especially phonology, functional load, or phonemic load, is the collection of words that contain a certain pronunciation feature (a phoneme) that makes distinctions between other words. Phonemes with a high functional load distinguish a large number of words from other words, and phonemes with a low functional load distinguish relatively fewer words from other words. The omission or mishearing of features with a high functional load thus leads to more confusion than features with a low functional load.
