i thought reference might apply but can it be used as a verb on its own because to my mind the way the clue indicates allude suggests that the answer is a verb but i may be over cautious tanx guys
Yes- you can 'reference' something. The verb 'to reference' is used quite often- for example in educational articles. Many words nowadays are used as verbs too- to action something for example. Some people dislike the trend to create verbs where they didn't exist before (eg I remember someone- John Humphreys I think- complaining about the verb 'to obsess') but as long as people understand it I'm not sure it matters
