Making allusions is a way of referring to something without directly mentioning it. To make an allusion, one can REFER, MENTION, INFER, or getat the subject. Referring to something is when one mentions it in passing, while mentioning something is when one explicitly states it. Inferring is when one implies something without directly saying it, and gettingat something is when one hints at it. All of these methods are ways of making allusions.
