Without a float; lacking floats or lacking the ability to float.
From float + -less (Old English suffix meaning 'without' or 'lacking'). This describes something that doesn't have floats or cannot float, using the productive -less suffix that attaches to nouns and verbs.
The -less suffix is fascinating because it works almost universally in English—you can put it on almost any noun (thankless, timeless, cloudless) and native speakers will instantly understand you mean 'without that thing,' even if the exact word is rare or invented.
