The word 只好 is formed through the conceptual blending of its two component characters: 只, which conveys limitation or exclusivity (meaning "only" or "merely"), and 好, which denotes acceptability or what is satisfactory ("good" or "well"). Their combination creates a new, unified idea not fully expressed by either character alone, specifically, the notion of having to accept or settle for a particular course of action because it is the only viable or remaining option, essentially "having no choice but to"... It is a semantic fusion where limitation meets pragmatic acceptance.
