verb (parallels, paralleling, paralleled)[with object]
mid 16th century: from French parallèle, via Latin from Greek parallēlos, from para- 'alongside' + allēlos 'one another'
Spell parallel with a double l before the e and a single l after it.
The different forms of the verb are spelled parallels, paralleling, paralleled (it does not follow the usual rule that a final l is doubled when adding endings which begin with a vowel to words which end in a vowel plus l).
