IPA: /nɒnˈbɒtənɪst/
KK: /nɑnˈbɑtənɪst/
A person who does not study or specialize in plants and botany.
Although she loves gardening, she is a nonbotanist and does not have formal training in plant science.
Nonbotanist → It is formed from "non-" (meaning not) and "botanist" (from Greek "botanistēs", meaning one who studies plants). The word "nonbotanist" refers to someone who is not a botanist or does not study plants.
Think of 'non-' meaning 'not' and 'botanist' as someone who studies plants. So, a nonbotanist is simply someone who does not study plants.
