The FFF submethod states that words can be named by Form, Feel, and Function.
• Some examples of naming words by Form include (a) the leg of a chair, (b) the handle of a pot, (c) the branch of a family tree, (d) surfing the net or (e) brainstorming Some of these examples illustrate naming objects by form while other examples illustrate naming activities by form.
• A good punchy example distinguishing naming by form vs. function is pentagon-UN. The pentagon is named after the shape and form of the building while the United Nations is named after the function and purpose of the building. Although both these buildings have as a purpose world peace they are named differently.
• Examples of naming by feel/substance are glasses, hardship, ironing-board, plaster etc.

The FFF principle is a special case of the literary techniques of synechdoche-metonomy. These literary principles, universal to all languages, state that items can be named by related items, by parts of those items, or by good examples of those items. For example honey refers to anything sweet since honey is a good example of something sweet. Similarly hot refers to matters of love since the two are related. Todays Rashi can best be understood by applying these principles.

Verse Lv25-09a discussing the requirements connected with the Jubilee year states ...pass a shofar blast ...throughout the land.....proclaim freedom throughtout the land. Rashi explains the passing of the shofar-blast metonomycally as meaning Announce the proclamation of freedom throughout the land by shofar blast. This interpretation names an activity - announcing the proclamation of freedom by shofar blast - by its form - the non physical shofar blasts appear to have the form of traveling / passing throughout the land.
