What Fsus4 is made of
Fsus4 (F suspended fourth) is built from the notes F, Bb, C, with the interval pattern 1, 4, 5.
Stack 1, 4 and 5 on a root of F and you get F, Bb and C. That interval recipe is what makes the chord a suspended fourth chord — move the same shape to another root and the character travels with it, which is why Csus4 sounds like a transposed Fsus4.
Suspended 4th: Tense, wants to resolve to the major.
Spelling: the notes above are written the way a score would write them, not simplified to the nearest piano key. That is why this chord is spelled with B♭ rather than its enharmonic equivalent.
