in a way that is not strong
In a way that is not strong; with little power, energy, or feeling.
用法パターン：
[someone] [verb] weakly
よくある間違い：
Learners sometimes confuse "weakly" with "weekly". "Weakly" means "in a weak way" and describes how something is done (adverb). "Weekly" means "every week" and describes how often something happens. Example: "He smiled weakly" (correct) vs. "He smiled weekly" (wrong). Learners also sometimes say "He is weakly" when describing a person. In that case, use the adjective: "He is weak," not "He is weakly."
類義語
feebly (Emphasizes physical weakness or lack of energy more strongly than "weakly".)
|
faintly (Suggests something is only just noticeable, often for sounds or lights, not always about strength of effort.)
|
poorly (Can mean "not well" in a general sense, including quality or health, not only lack of strength.)
対義語
strongly (General opposite, showing a lot of power, feeling, or effect.)
|
firmly (Opposite in contexts of physical pressure or mental resolve, stressing steadiness and strength.)
|
forcefully (Opposite when talking about speech or actions done with a lot of power or impact.)

in a mathematically weak sense
In math, science, or computing, in a way that follows an easier or less strict rule than the full or "strong" rule, often allowing equality.
用法パターン：
weakly [adjective] [noun]
よくある間違い：
Learners often interpret "weakly" here as simply "a little" or "slightly" and miss the formal meaning that a weaker or non-strict version of a condition is being used, usually in contrast with "strongly" or "strictly". In phrases like "weakly increasing," it does not just mean "increasing only a little"; it means "never decreasing and possibly staying equal."
類義語
non-strictly (Used mainly with inequalities in mathematics to mean that equality is allowed; very close in some contexts (e.g., non-strictly increasing).)
|
loosely (Sometimes used informally to mean "not in the strict sense," but less precise and more general than "weakly.")
対義語
strongly (Direct technical opposite, meaning the stronger or more restrictive version of a property holds.)
|
strictly (Opposite in the context of inequalities or conditions that do not allow equality or exceptions.)

表現
weakly acidic
1/wˈikli əsˈɪdɪk/
fixed phrase
technical
having low acid strength
Used in chemistry to describe a substance or solution that is an acid but not a strong one, often because it only partly breaks into ions in water.
例文
- Acetic acid is weakly acidic compared to hydrochloric acid.
- The solution is only weakly acidic, so it is not very dangerous to handle with care.
- Rainwater is usually weakly acidic due to dissolved carbon dioxide.
weakly basic
1/wˈikli bˈeɪsɪk/
fixed phrase
technical
having low base strength
Used in chemistry to describe a base that is not very strong, often because it does not take protons or form ions very easily in water.
例文
- Ammonia is weakly basic in water, so its pH is only slightly above neutral.
- The solution is weakly basic, with a pH just over 7.
- Some salts create a weakly basic environment when they dissolve.
weakly correlated
1/wˈikli kˈɔɹəlˌeɪtɪd/
fixed phrase
technical
having a small statistical link
Used in statistics to say that two variables are related, but only a little; the strength of the relationship is low.
例文
- Income and happiness are only weakly correlated in many studies.
- The two measurements are weakly correlated, so one does not predict the other very well.
- Although the variables are weakly correlated, the effect is still statistically significant.
weakly decreasing

fixed phrase
technical
mathematical non-increasing behavior
Used in math to describe a function or sequence that never goes up: it can go down or stay the same, but it does not go up.
例文
- The probability of error is weakly decreasing as the sample size grows.
- A weakly decreasing sequence can remain constant for many steps before it drops.
- If demand is weakly decreasing in price, raising the price will not increase the quantity demanded.
weakly increasing

fixed phrase
technical
mathematical non-decreasing behavior
Used in math to describe a function or sequence that never goes down: it can go up or stay the same, but it does not go down.
例文

- If the cost is weakly increasing in quantity, buying more never makes it cheaper per unit.
weakly typed
1/wˈikli tˈaɪpt/
fixed phrase
technical
programming language with loose types
Used about a programming language where the rules about data types are not very strict, so the computer may change types automatically or only find type problems when the program runs.
例文
- JavaScript is often described as a weakly typed language because it allows many implicit type conversions.
- In a weakly typed system, adding a number to a string may not cause an immediate error.
- Some developers prefer strongly typed languages, while others like the flexibility of weakly typed ones.
