You can also technically use "retard", but people will probably more often associate this with mental disability.
Retard, from M-W
to slow down the development or progress of (something)
If you mean to actively intervene and make something else slower, you can use impede. From Merriam-Webster:
To slow the movement, progress, or action of (someone or something)
Transitive verb - To interfere with or slow the progress of
- He claims that economic growth is being impeded by government regulations.
- The soldiers could not impede the enemy's advance.
For example, you could say "We thought that hiring more staff would quicken progess on this project, but actually, the extra hassle has impeded us".
This is a good choice if you want to emphasise that one thing is making another, different, separate thing slower (as opposed to something slowing naturally).
It's often used for abstract things. For example, "to impede progress" is a pretty common phrase.
To slow the movement, progress, or action of (someone or something.)
Construction is hampering traffic on the highway.
There is also decelerate, which is the opposite of accelerate.
to move slower : to lose speed
It has the effect of slowing down.
