Over-spreading refers to something that is excessively covering a surface or area. Its antonyms include words like sparse, thin, and barren. When something is sparse, it means that it is thinly dispersed, and there is not enough of it to cover the area thoroughly. The word thin implies that something is spread out, but it is not dense enough to cover the entire surface. Finally, barren indicates that the land or space is unproductive and lacks the necessary resources to support life. It is always useful to know antonyms since they help us to expand our vocabulary and express our thoughts more accurately.
