IPA: /dɪˈhɪsənt/
KK: /dɪˈhɪsənt/
Relating to the process of splitting open or bursting, especially in reference to plants or wounds.
The dehiscent fruit splits open to release its seeds when it is ripe.
Dehiscent is formed from "de-" (meaning down or away) and "hiscere" (meaning to split or gape). The word describes a plant structure that splits open to release its contents, such as seeds, hence the meaning of splitting away.
Think of something that 'splits open' ('hiscere') and 'away' ('de-') to release its contents, like a pod that opens to let seeds out.
