how are the creature's first words similar to teh typical first words of human babies?

He learns words in regards to "things" first, just like a baby. The words; fire. milk, bread, wood, and people's names are exactly like the first words a baby would learn. Example; where's the light; where's daddy; do you want bread? They're all nouns........... all naming words that have physical presence.

"By degrees I made a discovery of still greater moment. I found that these people possessed a method of communicating their experience and feelings to one another by articulate sounds. I perceived that the words they spoke sometimes produced pleasure or pain, smiles or sadness, in the minds and countenances of the hearers. This was indeed a godlike science, and I ardently desired to become acquainted with it. But I was baffled in every attempt I made for this purpose. Their pronunciation was quick; and the words they uttered, not having any apparent connection with visible objects, I was unable to discover any clue by which I could unravel the mystery of their reference. By great application, however, and after having remained during the space of several revolutions of the moon in my hovel, I discovered the names that were given to some of the most familiar objects of discourse; I learned and applied the words, fire, milk, bread, and wood. I learned also the names of the cottagers themselves. The youth and his companion had each of them several names, but the old man had only one, which was father. The girl was called sister, or Agatha; and the youth Felix, brother, or son. I cannot describe the delight I felt when I learned the ideas appropriated to each of these sounds, and was able to pronounce them. I distinguished several other words, without being able as yet to understand or apply them; such as good, dearest, unhappy.
