 Ostensive definitions typically depend on context and on experience. Suppose the conversational context renders one dog salient among several that are visible. Then one can introduce the name ‘Freddie’ through the stipulation “let Freddie be this dog.” For another example, suppose you are looking at a branch of a bush and you stipulatively introduce the name ‘Charlie’ thus: “let Charlie be the insect on that branch.” This definition can pin a referent on ‘Charlie’ even if there are many insects on the branch. If your visual experience presents you with only one of these insects (say, because the others are too small to be visible), then that insect is the denotation of your use of the description ‘the insect on that branch’. We can think of experience as presenting the subject with a restricted portion of the world. This portion can serve as a point of evaluation for the expressions in an ostensive  definition.[2]  Consequently, the definition can with the aid of experience pin a referent on the defined term when without this aid it would fail to do so. In the present example, the description ‘the insect on that branch’ fails to be denoting when it is evaluated at the world as a whole, but it is denoting when it is evaluated at that portion of it that is presented in your visual experience. See Gupta 2019 for an account of the contribution of experience to the meaning of an ostensively defined term.
