What does feebleness mean?
Feebleness is the quality of being weak, frail, or lacking in force, whether in body or in effect. In its most literal sense it describes diminished physical strength — the feebleness of old age, illness, or exhaustion — but it is equally applied to abstract matters: the feebleness of an argument, a policy, or an apology signals that it lacks conviction, substance, or impact. Because of this breadth, the word often carries a subtly critical tone; to call a response feeble is rarely neutral. It derives from the adjective "feeble", which English borrowed via Old French from Latin flebilis, meaning "lamentable" or "to be wept over", from the verb flere, "to weep". The word sits alongside near-synonyms such as weakness, frailty, debility, and infirmity, each shading the idea differently: frailty emphasises delicate fragility, infirmity suggests chronic or age-related condition, while feebleness stresses evident inadequacy. It remains a useful, precise term whenever weakness needs naming without euphemism.
The state or quality of being weak in body; lack of physical strength or vigour.
"The feebleness of his limbs after the stroke required round-the-clock care."
Often used compassionately when describing age or illness.
Lack of force, effectiveness, or conviction in something non-physical, such as an argument, effort, or performance.
"Voters were unimpressed by the feebleness of the opposition's rebuttal."
Carries a distinctly critical, evaluative tone in this sense.
Rarely used; the plural appears only when counting distinct instances of weakness, and most writers prefer singular or rephrasing.
"The report catalogued the feeblenesses of successive administrations' climate policies."
"Feeble" comes from Latin flebilis — literally "lamentable" — so calling something feeble once carried the sting of saying it deserved to be wept over.

Etymology of feebleness
Feebleness derives from the adjective "feeble", which entered English in the Middle Ages through Old French feble from Latin flebilis, "that is to be lamented", formed on flere, "to weep". The abstract noun feebleness was formed from the adjective, following the common English pattern of -ness suffixation. Cognate forms include the derived verb "enfeeble", reflecting the same Latin root's path through French.

How feebleness is actually used
Feebleness is somewhat formal in register and frequently carries a faint negative connotation of inadequacy, not merely physical weakness. It is often used evaluatively about non-physical things — arguments, excuses, responses — where it implies disappointing lack of substance or force.
Easily confused with feebleness
Weakness is a broader term covering lack of power or a vulnerable point, while feebleness specifically suggests pronounced, often visible frailty or ineffectuality.
Frailty refers especially to delicate physical fragility (often of age or health), whereas feebleness can also describe weakness of character, argument, or effort.
