deliquesce
LowFormal, Literary, Technical/Scientific
Definition
Meaning
To melt away or dissolve, typically becoming liquid by absorbing moisture from the air.
To melt away, disappear, or become liquid, often as a chemical process or metaphorically to describe something gradually losing form or structure.
Linguistics
Semantic Notes
Primarily intransitive verb. In scientific contexts, refers specifically to salts absorbing atmospheric moisture and dissolving into a solution. In literary use, describes gradual dissipation or disintegration of form, will, or substance.
Dialectal Variation
British vs American Usage
Differences
No significant differences in core meaning. Slightly higher usage in British technical writing (chemistry, mycology).
Connotations
Both share formal/scientific connotation. Literary use may be slightly more common in British English.
Frequency
Very low frequency in both varieties; perhaps marginally more likely in British academic texts.

Usage
Context Usage
Business
Virtually never used.
Academic
Used in chemistry, materials science, and literary criticism to describe dissolution.
Everyday
Extremely rare; would sound highly formal or pretentious.
Technical
Precise term in chemistry for solids (especially salts) absorbing moisture from air until dissolving.
Examples
By Part of Speech
verb
British English

American English
- Certain salts will deliquesce if left uncovered in a humid climate.

Examples
By CEFR Level
- The sugar will deliquesce if the jar is not closed properly.
- Salt can deliquesce on a very humid day.

Learning
Memory Aids
Mnemonic
Think: 'DE-LIQUESCENT' → sounds like 'become liquid'. Imagine a solid becoming a puddle (LIQUID) in the DEW.
Conceptual Metaphor
SOLIDITY IS STABILITY / LIQUIDITY IS DISSOLUTION OR LOSS OF FORM. Used metaphorically for loss of willpower, structure, or integrity.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'разжижать' (to liquefy generally). Deliquesce is specifically intransitive and often implies absorption of ambient moisture.
- Not synonymous with 'таять' (to melt from heat). It is a specific physicochemical or literary process.
- Avoid using for simple disappearance; it implies a physical change of state.
Common Mistakes
- Using it transitively (e.g., 'The heat deliquesced the ice' – incorrect).
- Confusing with 'effloresce' (to lose water of crystallization to air).
- Using in casual contexts where 'melt' or 'dissolve' would suffice.

FAQ
Frequently Asked Questions
Primarily, yes. Its core, literal meaning is scientific (chemistry, mycology). However, it is used metaphorically in literary or formal writing to describe something melting away or losing form.
All deliquescing is dissolving, but not all dissolving is deliquescing. 'Deliquesce' is intransitive and specifically means to dissolve by absorbing moisture from the air. 'Dissolve' is more general and can be transitive (dissolve sugar in water) or intransitive.
Yes, but only in a highly figurative, literary sense. For example, 'His anger deliquesced into weary resignation' suggests a gradual melting away of a strong emotion. This usage is rare and formal.
The related nouns are 'deliquescence' (the process) and 'deliquium' (an archaic/literary term for a swoon or liquefaction). The adjective is 'deliquescent'.
