Perfect vs. Simple

ភាពខុសគ្នារវាង Present Perfect និង Past Simple

It's all about Finished Time vs. Time Connected to Now!

វាអាស្រ័យលើពេលវេលា! តើវាជាពេលវេលាដែលបានបញ្ចប់ហើយ ឬនៅមានទំនាក់ទំនងមកដល់បច្ចុប្បន្ន?

history

history 1. Past Simple

ពេលវេលាដែលបានបញ្ចប់ (Finished Time)

We use Past Simple with specific, finished time words:
(yesterday, last week, in 2020)

I went to Paris in 2019.

ខ្ញុំបានទៅទីក្រុងប៉ារីសក្នុងឆ្នាំ ២០១៩។

She finished it yesterday.

នាងបានធ្វើវាចប់កាលពីម្សិលមិញ។

all_inclusive

all_inclusive 2. Present Perfect

បទពិសោធន៍ ឬពេលវេលាមិនទាន់ចប់ (Unfinished)

We use Present Perfect for experiences or unspecific time:
(ever, never, already, yet, today)

I have been to Paris.

ខ្ញុំធ្លាប់ទៅទីក្រុងប៉ារីស។ (បទពិសោធន៍ជីវិត)

She has already finished it.

នាងបានធ្វើវាចប់រួចរាល់ហើយ។ (លទ្ធផលនៅបច្ចុប្បន្ន)

warning The Time Marker Trap!

NEVER use Present Perfect with finished time words!

(ប្រយ័ត្ន! កុំប្រើ Present Perfect ជាមួយពាក្យបញ្ជាក់ពេលវេលាដែលកន្លងហួស ដូចជា yesterday, last year ឲ្យសោះ!)

I have seen him yesterday. close
I saw him yesterday. check

Teacher, can I say "I have lived here for 5 years"?

Yes! That is perfect. That means you started living here in the past, and you STILL live here now. If you say "I lived here for 5 years" (Past Simple), it means you don't live here anymore!

What about "this morning"? Is it finished or unfinished time?

It depends on what time it is NOW! If it is still morning (10:00 AM), use Present Perfect: "I have drunk coffee this morning." If it is now afternoon (2:00 PM), the morning is finished. Use Past Simple: "I drank coffee this morning."
