IPA: /ˌʌn.məˈlɛs.tɪd/
KK: /ʌnˈmɑlɛstɪd/
Not disturbed, harmed, or interfered with in any way.
The garden was left unmolested, allowing the flowers to bloom freely.
Unmolested → It is formed from "un-" (meaning not) and "molestus" (from Latin, meaning troublesome or annoying). The word "unmolested" means not troubled or disturbed.
Think of 'not' ('un-') being combined with 'troublesome' ('molestus') to remember that 'unmolested' means not being troubled.
