reinforce

reinforce:

1 to make something stronger:
The pockets on my jeans are reinforced with double stitching.

2 If something reinforces an idea or opinion, it provides more proof or support for it and makes it seem true:
The final technical report into the accident reinforces the findings of initial investigations.
His behaviour merely reinforced my dislike of him.

3 to provide an army with more soldiers or weapons to make it stronger:
The garrison is to be reinforced with/by another two battalions of soldiers.
