Questions & Answers about Και εγώ προσπαθώ να εκφράζω το πάθος μου για τα ελληνικά προκειμένου να μην τα παρατήσω.

Why do we need και at the beginning (Και εγώ προσπαθώ…)? Could we just say Εγώ προσπαθώ…?

Και here means “also / too” and connects this sentence to something previously said, e.g. “My friend studies Greek, and I also try to express my passion for Greek…”.

• Και εγώ = I also / me too.
• If you say only Εγώ προσπαθώ…, it’s grammatically fine but it means “I try…” with more emphasis on I (contrasting with someone else), not also.
• In natural speech, if this is a standalone sentence, you might simply say Προσπαθώ να εκφράζω… (omitting both και and εγώ, because the verb ending already shows the subject).

So:

• Και εγώ προσπαθώ… = “I also try…”
• Εγώ προσπαθώ… = “I (as opposed to others) try…”
• Προσπαθώ… = Neutral “I try…” with no contrast or “also” meaning.

What is the difference between προσπαθώ να εκφράζω and προσπαθώ να εκφράσω?

Both are correct but they differ in aspect and nuance:

• Προσπαθώ να εκφράζω: present subjunctive
  Implies trying to do something repeatedly / habitually / as an ongoing way of behaving.
  → “I try to be expressing / keep expressing my passion (as a habit, in general).”

• Προσπαθώ να εκφράσω: aorist subjunctive
  Implies trying to achieve a single, complete act of expression, or specific occasions.→ “I’m trying to express my passion (this time, in this particular case / moment).”
