Questions & Answers about אחרי האימון אין לי כוח לעלות במדרגות.

Why is there no Hebrew verb meaning have in אין לי כוח?

In modern Hebrew, possession in the present tense is usually expressed with יש ל־ / אין ל־ rather than with a normal verb meaning have.

• יש לי כוח = I have strength / energy
• אין לי כוח = I don’t have strength / energy

Literally, אין לי כוח is something like there is not to me strength.

This is very common in Hebrew:

• יש לי זמן = I have time
• אין לי כסף = I don’t have money

So the sentence does not need a separate word for have.

What exactly does אין לי כוח mean? Is it just I can’t?

Not exactly. אין לי כוח usually means:

• I don’t have the energy
• I’m too tired
• sometimes even I can’t be bothered

It is often more about energy, strength, or motivation than pure ability.

Compare:

• אני לא יכול לעלות במדרגות = I can’t go up the stairs
  (maybe physically impossible, or not allowed, or some other reason)
• אין לי כוח לעלות במדרגות = I don’t have the energy to go up the stairs

So this sentence sounds more like fatigue than inability in a strict sense.
