Have you ever asked yourself does anything rhyme with orange?? I have
(aka i was bored and heard it on tv and they said nothin BUT WALA)
Orange is one of those words that famously has nothing perfectly to rhyme with it. The other one is silver. However, the Oxford Rhyming Dictionary does show both these words as having half-rhymes (such as lozenge with orange and salver with silver).
The principle of a half-rhyme in these cases is quite simple. Whereas a full and stressed rhyme (e.g. hand / stand) or even an unstressed rhyme (such as handing / standing) contain vowels that are common to both words, a half-rhyme like orange / lozenge or silver / salver (technically speaking, pararhymes) has obvious differences between vowels in certain syllables.
