What does thaw mean?
“Thaw” means to melt or to become liquid, usually referring to ice, snow, or a frozen substance. It can also describe a gradual lessening of coldness, strictness, hostility, or emotional tension: a frozen lake may thaw in the sun, while difficult relations may thaw through patient negotiation. The verb commonly appears in literal weather and seasonal contexts, such as frozen ground beginning to thaw in spring. Figurative uses often carry a cautiously positive implication, suggesting that barriers are softening and communication may become easier. “Thaw” can likewise be a noun for a melting period or a shift toward less tension, as in “a thaw in relations.” The word is used in standard British and American English without a major regional distinction, and its figurative meaning has become especially familiar in political and diplomatic language.
To melt, especially as ice or snow changes from a solid into a liquid; to become less tense, hostile, or restricted.
"The river began to thaw after several days of unusually warm weather."
The figurative meaning is common in discussions of relations, negotiations, and personal emotions.
A period during which frozen material melts, or a gradual easing of tensions or restrictions.
"The thaw in diplomatic relations finally created room for negotiations."
The plural is used for separate periods of melting or for multiple instances of tensions easing.
"Brief thaws in the weather gave way to several weeks of freezing rain."
The word “thaw” is older than many modern English words: Old English had its own verb, þawian, for ice and snow turning to water.

Where does thaw come from?
The English verb descends from Old English þawian, meaning “to melt” or “to turn to water.” It developed from a Germanic root associated with melting, and related forms appear in languages including German, Dutch, and Old Norse. In English, the literal sense was established before the modern figurative use for the easing of political or personal tensions.

The literal sense is neutral and common in everyday English. The figurative sense is especially frequent in political, diplomatic, and interpersonal contexts, where it suggests that tensions are becoming less severe rather than that all disagreements have disappeared.
