# Six undefined words

• X is an important part of something. That 'something' is a constituent of Y and depends on Z.
• A, B and C are important parts of another something. This 'something' is also a constituent of Y and depends on X and Z.

Identify X, Y, Z and A, B, C with the help of the following three operations.

Operation 1 (Examples)

Before After
Crime Prime
Toast Boast
A X

Operation 2 (Examples)

Before After
Smile Miles
Phase Shape
B Y

Operation 3 (Examples)

Before After
Flick Lick
Bring Ring
C Z

• Is the 'something' referred to in the two bullet points the same 'something', or two different 'somethings'?

• @Stiv Different 'somethings'. I'll modify the post to make it clear. Sep 13, 2022 at 18:02
• Would [Mouth -> Youth] fit operation 1? Sep 14, 2022 at 3:29
• @Chengarda Yes. It would. Sep 14, 2022 at 5:06

This is the best I have so far:

A = Hand B = Heart C = Brain
X = Land Y = Earth Z = Rain

Land is an important part of Earth's surface. The surface is a constituent of Earth and depends on Rain. Hand, Heart and Brain are important parts of a Human. The Human is also a constituent of Earth and depends on Rain and Land.

It's possible I have it partially correct, or maybe not correct at all.

• Amazing job to have cracked this! For the sake of satisfaction, can you change A and X to five letter singular words? Your answer is valid as it is now but I had five letters in mind. Sep 14, 2022 at 8:25

Given the previous answer and request to change "A and X to five letter singular words", I'll go with

A = liver, X = river

(I'd rather have made a comment - but just startet here without reputation.. ;) )

• That was the answer I was looking for! Nice.. Sep 14, 2022 at 19:44
