tutor
俾 centers on a person who guides or instructs another: a tutor. The meaning is narrow and specific to a teaching or mentoring role.
俾 combines 亻 (person) with 卑, which likely contributes the sound. The exact historical development is uncertain, but the structure suggests a person associated with the concept represented by 卑.
A person 亻 beside 卑: imagine a humble tutor bowing slightly while patiently explaining a lesson. The tutor's modest posture helps you remember the meaning.
For フ, picture a tutor teaching the sound of the wind: "foo" (フ) as they blow gently to demonstrate. The soft "foo" sound cues the reading フ.
