The phrase "short supplies" is often used to express the scarcity of certain items. However, there are many synonyms that can be used to convey the same idea. Terms such as "limited resources," "insufficient stock," "scarce materials," "restricted quantities," and "sparse provisions" are all useful alternatives. Other phrases that can be used include "meager supplies," "inadequate inventory," "scanty resources," "low stock levels," and "deficient amounts." Choosing the right synonym will depend on the context and the tone of the conversation or document in question. The goal is to convey a sense of scarcity without being overly negative or alarmist.
