Questions & Answers about Ego saepe cogito utrum amica mea cras ventura sit.
Yes. The ending of cogito already tells you the subject is I, so ego is not grammatically necessary.
Latin often leaves subject pronouns out unless they are needed for:
- emphasis
- contrast
- clarity
So Ego saepe cogito... can feel like:
- I often think...
- As for me, I often think...
If you removed ego, the sentence would still be perfectly grammatical:
- Saepe cogito utrum amica mea cras ventura sit.
Utrum introduces an indirect yes/no question. Here it means whether.
So:
- utrum amica mea cras ventura sit = whether my girlfriend/female friend is going to come tomorrow
In Latin, indirect questions are commonly introduced by words like:
- utrum = whether
- num = whether
- interrogative words such as quis, quid, cur, ubi, etc.
You will often see utrum ... an ... when both alternatives are expressed:
- utrum veniat an maneat = whether she is coming or staying
In your sentence, only one side is stated, so utrum alone is enough.
