It is a preposition.

You can use the word "constitution" to describe animals, robots and infrastructures. However it sounds kind of formal / poetic and dare I say like you are trying to show off your vocabulary (nothing wrong with that). Synonyms like: structure, build, design, or makeup would feel more natural to me. But it depends on what you are writing.

Historically, "limelight" referred to a type of stage lighting created by heating a cylinder of lime with an oxyhydrogen flame, which produced a bright, focused beam. That’s where the phrase to be in the limelight comes from—it originally meant being at the center of attention on stage. Today, it’s used more broadly to mean being in the public eye. To be in the spotlight is a more modern version with the same meaning. Both expressions are still commonly used, and neither one has a particularly positive or negative tone—they’re generally neutral.

I felt really sad today. They announced that my favourite video game is being shut down / scaled back (choose whichever fits). This game has meant a lot to me—it’s influenced my life in so many ways, and I’ve made some great friends through it. All I can do now is keep enjoying it while it lasts.

Today and yesterday, I had a part-time job. I’m very tired. I have to do my homework. I have three reports, and a normal homework.But maybe I can’t. I’m too sleepy now… I’ll do my homework tomorrow night. In this Sunday, I’m going to go to the concert. It’s a joint concert, so I can see many artists! I have to enjoy the concert, so I have to finish my homework!
