thank you for your nice words Ms. Sue:)

You're very welcome, Astasia.

The word "principle" can have different meanings depending on how it is used in a sentence. Here are explanations for each sentence:

1. In this context, "principle" means the main or primary reason. To understand this, you would need to identify the subject and verb of the sentence, which are "baby" and "was." Then, you would look for the word that describes the reason for his happiness, which is "principle." So, the baby is the main reason for his happiness.

2. Here, "principle" refers to the main or most important facts. To identify this meaning, you would need to find the subject and verb of the sentence, which are "jury" and "heard." Then, you would look for the word that describes the facts heard by the jury, which is "principle." So, the jury heard only the main or most important facts.

3. In this case, "principals" is a misspelling, and it should be "principles." "Principles" means the standards or beliefs that guide someone's behavior or decisions. To understand this, you would identify the subject and verb of the sentence, which are "facts" and "upset." Then, you would look for the word that actually upsets the speaker, which is "principles." So, it's not the facts that upset me, but rather the standards or beliefs of the case.

4. Again, "principle" means the main or primary reason here. To understand this, you would need to identify the subject and verb of the sentence, which are "hay fever" and "was." Then, you would find the word that describes the reason for his sneezing, which is "principle." So, his hay fever is the main reason for his sneezing.

5. In this context, "principle" refers to strong moral beliefs or values that someone possesses. To understand this, you would identify the subject and verb of the sentence, which are "she" and "was." Then, you would look for the word that describes her, which is "principle." So, she is a person with strong moral beliefs or values.
