Pronunciation & Spelling
None of these words rhymes exactly with 'weightless'. The '-less' words (worthless, restless, tasteless, useless) share the unstressed suffix /ləs/ but have different stressed vowels. 'freight' and 'eight' match the 'eigh' spelling and /eɪ/ sound of the first syllable of 'weightless', but they do not rhyme with the whole word. Beware 'tasteless': despite its similar spelling, it has /stləs/ rather than /tləs/ and does not rhyme.
