IPA: /ˌɪntərˌdɪdʒɪˈteɪʃən/
KK: /ˌɪntərˌdɪdʒɪˈteɪʃən/
A way in which two things fit together or interlock, similar to how fingers interlace when hands are clasped.
The interdigitation of the two materials created a strong bond.
Interdigitation → It is formed from "inter-" (meaning between) and "digitus" (meaning finger). The word describes the action of fingers interlocking or intertwining with each other, as in a gesture of connection or grasping.
Think of fingers 'between' each other ('inter-') — that's why interdigitation means fingers interlocking.
