Questions & Answers about Ya he encendido la pantalla.
Why doesn't ya (already) go between he and encendido like it does in English?
In Spanish, the helping verb (he) and the past participle (encendido) are practically glued together. You can never put another word between them. Words like ya usually go right before the conjugated helping verb.
How do we know to use he here instead of tengo for "I have"?
When "have" is used as a helping verb to talk about something you have done (like "I have turned on"), you must use a form of haber, which is he for "I". You only use tener (like tengo) when you mean "to possess" something.
How is the word encendido formed here?
It comes from the verb encender (to turn on). To make the past participle (the "turned" part of "have turned"), you take off the -er ending and add -ido. If it were an -ar verb, you would add -ado instead.
Does encender only mean to turn on a screen?
You use encender for turning on electronics, like screens, computers, or lights. It literally means "to light" or "to ignite," so it is also the word used for lighting a fire or a match.
