1. speeches made by characters in a story = dialogue
Dialogue refers to a speech in which at least two people are talking. In literature, there are different types of speeches: we have monologues (when only one person is talking and others are listening), soliloquys (when one person is alone and speaking), dialogues (when at least two people are speaking to each other), etc. 

2. present-day = contemporary
The word contemporary comes from Latin, where con- means together, and tempus means time. So literally, this word means 'together with time,' which can be roughly translated as now, in the present, at the moment, at the moment of speaking.

3. struggle within one person's mind = internal conflict
There are many types of conflict, which refers to some kind of struggle. You can have a conflict within yourself (internal conflict), a conflict with another person (man vs. man), a conflict with a lot of people (man vs. society), or generally with life (man vs. nature).

4. talkative = garrulous
Like many words in English, the word garrulous also comes from Latin. It is derived from Latin verb garrire, which means to chatter, to prattle (which means to talk excessively). So the adjective garrulous in contemporary English refers to someone who is talking a lot about something trivial.

5. all-seeing, all-knowing = omniscient
Like many words mentioned above, the word omniscient also comes from Latin. It is derived from Latin pronoun omnis (meaning everything), and verb scire (meaning to know). So when translated literally, omniscient means to know everything. 

6. submissive = obsequious
The word obsequious also comes from Latin; it is derived from the verb obsequi, which means to follow, to comply with. When added the English suffix for adjectives -ous, the word obsequious represents a servile person, someone who is practically grovelling before someone more powerful.

7. a single happening in a story = incident
Incident, also known as event, is a happening within a story. It can refer to something rather small and unimportant, or something crucial that can change the course of the story. When referred to several incidents/events together, we are talking about plot of a story.

8. savage = barbarian
When this word was created, barbarian was used to denote a person who wasn't a part of a great civilization such as Christian, Roman, or Greek. Over time, the meaning changed slightly to denote someone who is very crude, uncultured, or brutish. 

9. necklace = riviere
Although the word riviere literally means river in French, it is used in English to refer to a type of a necklace. It is a specific kind of a necklace - usually made of diamonds or other gemstones of same kind and size, connected in order to create a beautiful decoration.

10. weird = eerie
The word eerie comes from Old Germanic languages, and refers to something strange, weird, but also a bit frightening. Today, it is usually used to refer to mysterious and creepy locations (usually in horror and suspense stories, such as in those written by Poe).
