Students of Rashi must bear in mind that Rashi could sometimes use universal principles applicable in all languages. This particularly applies to the meaning methods.

The synechdoche principle basically says that any language can use a good example to name an entire category. For example, in English,
• the word honey can mean anything sweet.
• Similarly bread can refer to any food.
• Man can refer to any person (male of female)
• day can refer to the entire 24 hour period
• heart can refer to the entire person as in e.g., (Ps 43)My heart yearns for you, God which really means My entire person yearns for you God
• The loss of a person can refer to the destruction of that person (Dt28-22i)

Hence Rashi translates Cheth-Nun-Teth flower sprouting as also meaning enbalming, an activity leading to pleasing odors since flower-sprouting and enbalming are both good examples (Synechdoche) of activities creating pleasant odors/aromas.

As shown by the underlined words, Rashi uses this translation in the following verse Gn50-02a And Joseph commanded his servants the physicians to embalm [with sprouts of flowers used by embalmists] his father; and the physicians embalmed Israel [with sprouts of flowers used by embalmists]

Advanced Rashi: Several other meaning rules are possible here. For example the triple FFF rule states that meaning is determined by Form, Function, and Feel. In fact the function/purpose of both flowers sprouting and of embalming are the emission of pleasant aromas. Such use of multiple rules reinforces the understanding of the meaning.
