Delicately weak can be described using a variety of synonyms that capture the fragility and slightness of this state. One possible synonym is "brittle," which suggests a tendency to break or shatter under pressure. Another option is "fragile," which implies a delicacy or vulnerability that requires careful handling. "Feeble" or "frail" could also be used to convey a sense of weakness, particularly in terms of physical strength or stamina. "Tenuous" or "tentative" might be more appropriate when describing a situation or position that is only weakly supported or maintained. Ultimately, the choice of synonym will depend on the specific context and intended meaning.
