IPA: /ˈfɛkləsnəs/
KK: /ˈfɛk lɪs nəs/
The quality of being ineffective or lacking in initiative and strength; a state of being irresponsible or incompetent.
His fecklessness in managing the project led to its failure.
Fecklessness is derived from the Scots word "feckless" (meaning ineffective or lacking in purpose), which itself comes from "feck" (meaning effect or value) combined with the suffix "-less" (meaning without). The term "fecklessness" thus refers to the state of being without effect or value, indicating ineffectiveness or irresponsibility.
Think of being 'without' ('-less') any 'effect' or 'value' ('feck') — that's why fecklessness means a lack of effectiveness or purpose.
