Yes. It's called Key Signature.
If you were to play in the Key of G, for example, You would build from G Major. So, to remain in key, the 7 notes in the G Major scale need to share harmony with each other. Chords require three notes minimum to function and need to relate with each other.
The 7 notes that make up the G Major scale are;
G-A-B-C-D-E-F# . The G Major chord uses G-B-D (1st,3rd,5th)
The next note of the 7 total is A. The A Major Chord Uses A-C#-E. (1st,3rd, 5th). Something's wrong . The 3rd of A Major is C#, which is not one of the seven notes in the key. If the 3rd in A Major is flattened by 1/2 step, the C# lowers to C. Now we have A-C-E (1st,b3rd,5th) and that fits the key.
Since we needed to alter the A Major chord by flattening the 3rd, it now becomes an A minor Chord. The 3rd interval in the Major scale must remain unaltered to be Major. Flattening the 3rd by 1/2 step creates the minor, sharpening the 3rd by raising it 1/2 step cancels out because it lands on the 4th interval, creating a Suspended 4th Chord and remains in key.
Gsus4 uses G-C-D (1st,4th,5th) but with the 3rd not present, means it's not Major or minor. It's suspended.
Let's look at the 4th interval in G to make a strong determining factor with relative notes.
C is the 4th of G, let's use the interval pattern from the Major scale, apply it to C and see what type of C chord is needed to fit in the key of G.
the C Major scale; C-D-E-F-G-A-B. Well, G has a F#, but C has an F. They both share 6 of the 7 notes. Does one off note really matter? let's see.
The C Major chord uses C-E-G (1st,3rd,5th) the C Major chord fits the key. What about Csus4? C-F-G (1st,4th,5th) Doesn't fit. The 4th (F) needs to be sharpened 1/2 step to F# in order to fit in the key of G, which now becomes; C-D-E-F#-G-A-B,,, And The C Lydian Mode.
