Having no extremes; showing no extreme values, positions, or variations; moderate and balanced throughout.
From extreme + -less (suffix meaning lacking or without). A descriptive adjective created through standard English word formation combining a concept with the negating suffix.
While grammatically valid, 'extremeless' is rarely used—we prefer words like 'moderate' or 'balanced'—but it perfectly captures the idea of something that never goes to extremes, which is kind of boring!
