IPA: /ˌɪnˈdɛlɪkəsi/
KK: /ɪnˈdɛlɪkəsi/
The quality of being rude or lacking sensitivity in behavior or speech.
His indelicacy during the meeting made everyone uncomfortable.
Indelicacy is formed from "in-" (meaning not) and "delicatus" (from Latin, meaning delicate or refined) and the suffix "-cy" (meaning the state or quality of). The word refers to the state of being not delicate, often implying a lack of tact or propriety.
Think of 'not delicate' ('in-' means not and 'delicatus' means delicate) to remember that 'indelicacy' refers to a lack of tact or refinement.
