The correct spelling for the phrase "were trail of" is actually "word trail of." The confusion in spelling may come from similar sounding words, but the IPA phonetic transcription can help clarify the difference. "Word" is pronounced as /wɜːrd/, while "were" is pronounced as /wɛr/. The differences can be heard in the vowel sounds, with "word" having a longer /ɜː/ sound, while "were" has a shorter /ɛr/ sound. It's important to pay attention to these differences and choose the correct spelling to convey your intended meaning.
