IPA: /səˈplɛtɪv/
KK: /səˈplɛtɪv/
Referring to a grammatical form that is created by using a completely different word instead of a regular inflection, such as using 'better' instead of 'good' for comparison.
In English, the words 'good', 'better', and 'best' are examples of suppletive forms.
Suppletive → It is formed from "suppletus" (meaning filled up or completed) and the suffix "-ive" (meaning having the nature of). The word "suppletive" refers to something that serves to fill in or complete a gap, particularly in grammar.
Think of something that 'fills in' or 'completes' a gap — 'suppletus' means filled up, and '-ive' indicates a quality. This helps you remember that 'suppletive' refers to something that serves to complete.
