Ability with قدر and b-Imperfect Forms

Lebanese قدر / بيقدر expresses ability through an ordinary finite verb: بقدر ساعدك “I can help you,” قدرت افتح الباب “I managed to open the door.” The b-imperfect form presents current or general capacity; the perfect commonly reports that someone managed to carry out a particular action.

This differs structurally from suffixed فيني, even though the two overlap in meaning. بقدر conjugates for the able person, then selects a bare action complement.

For the contrasting suffixed construction, see Ability and Possibility with في.

The focused b-imperfect paradigm

Urban ق is pronounced ʾ, so written بقدر is read bʾdar. The verb itself carries full agreement:

you feminineبتقدريbtʾadre
heبيقدرbyʾdar

بقدر إقرا عربي، بس شوي شوي.

bʾdar iʾra ʿarabe, bass shwayy shwayy.

I can read Arabic, but slowly. (informal; acquired capacity)

إنتي بتقدري تسوقي بالليل؟

inte btʾadre tsūʾe bil-lēl?

Can you drive at night? (informal; feminine agreement on modal and action)

هني بيقدروا يخلصوا الشغل اليوم.

hinne byʾdaro ykhalliṣo esh-shoghol el-yōm.

They can finish the work today. (neutral; plural agreement)

💡
بقدر is already the b-marked modal. Mark the lower action for person, but do not add another b-: بقدر ساعدك, not بقدر بساعدك.

The complement is bare but still finite-looking

The lower verb agrees with its actor. In the ordinary same-subject chain, both verbs point to the same person.

منقدر نبعت الملف قبل الظهر.

mniʾdar nbaʿat el-malaf ʾabel eẓ-ẓohor.

We can send the file before noon. (neutral/professional; first-person plural modal and bare action)

بتقدروا تحكوا أبطأ شوي؟

btʾdaro tiḥko abṭaʾ shwayy?

Can you all speak a little more slowly? (polite informal request; plural agreement)

When the actor of the lower action differs from the person whose ability is at issue, use an explicit causative or complement structure rather than letting the two agreeing verbs silently point to different people.

Inherent, learned, and achieved ability

The b-imperfect readily describes a capacity someone has. For learned know-how, بعرف + bare verb is also common and can foreground knowing how rather than physical or practical capacity.

بعرف سوق، بس ما بقدر سوق مسافة طويلة.

baʿrif sūʾ, bass ma bʾdar sūʾ masēfe ṭwīle.

I know how to drive, but I can't drive a long distance. (informal; know-how versus present capacity)

The perfect often implies successful achievement in a specific situation:

قدرت إفتح الباب بعد عشر دقايق.

ʾdert iftaḥ el-bēb baʿd ʿashar dʾāyeʾ.

I managed to open the door after ten minutes. (informal; achieved ability)

ما قدرت لاقي موقف قريب.

ma ʾdert lāʾe mawʾef ʾrīb.

I couldn't manage to find a nearby parking spot. (informal; failed attempt in one event)

English could is ambiguous between general past ability and success on one occasion. Lebanese perfect قدرت commonly highlights the achieved or failed result.

💡
Do not choose قدرت merely because English has could. First ask whether the sentence reports a bounded attempt and its outcome; for present capacity, use the b-imperfect.

Contrast with suffixed في

Both constructions can describe situational ability:

FormFrequent perspectiveExample
فيني + barecircumstances permit; permission or availabilityفيني إجي بعد الخمسة
بقدر + barecapacity, effort, or managing the actionبقدر إجي لحالي
قدرت + barespecific successful achievementقدرت إجي رغم الزحمة

فيني إجي بعد الخمسة لأنو بكون خلصت شغل.

fīne izhe baʿd el-khamse laʾanno bkūn khallaṣt shoghol.

I can come after five because I'll have finished work. (informal; availability from circumstances)

بقدر إجي لحالي، ما في داعي تمرق تاخدني.

bʾdar izhe la-ḥāle, ma fī dēʿe timroʾ tēkhodne.

I can come by myself; there's no need for you to pick me up. (informal; personal capability)

This is not an absolute lexical split. A speaker may choose فيني or بقدر in the same practical situation, with only a small change in framing.

Negation and short answers

Because بقدر is a b-imperfect verb, ordinary negation is ما بقدر. The lower action stays bare.

بقدر ساعدك اليوم.

bʾdar sāʿdak el-yōm.

I can help you today. (informal affirmative ability)

ما بقدر ساعدك اليوم، عندي موعد.

ma bʾdar sāʿdak el-yōm, ʿinde mawʿed.

I can't help you today; I have an appointment. (informal negative ability)

Short answers may repeat only the modal: إيه، بقدر “Yes, I can”; لأ، ما بقدر “No, I can't.” There is no do-support.

A dialogue contrasting capacity and opportunity

بتقدر تصلح الكمبيوتر؟

btʾdar tṣalleḥ el-kombyūtar?

Maya: Can you fix the computer? (informal dialogue; asks about capacity)

إيه، بقدر صلحه، بس اليوم ما فيني. عندي شغل كتير.

ē, bʾdar ṣalleḥo, bass el-yōm ma fīne. ʿinde shoghol ktīr.

Jad: Yes, I can fix it, but I can't today. I have a lot of work. (informal dialogue; general capacity versus current availability)

Common Mistakes

Keeping b- on both verbs

❌ بقدر بساعدك.

Incorrect — the modal bears b-, while its action complement is bare.

✅ بقدر ساعدك.

bʾdar sāʿdak.

I can help you.

Leaving the modal unconjugated

❌ هني بقدر يروحوا.

Incorrect — both the modal and lower action must agree with plural هني.

✅ هني بيقدروا يروحوا.

hinne byʾdaro yrūḥo.

They can go.

Using the perfect for general current capacity

❌ أنا قدرت إحكي عربي.

Incorrect for the intended general statement ‘I can speak Arabic’ — قدرت normally presents a bounded past achievement here.

✅ أنا بقدر إحكي عربي.

ana bʾdar iḥke ʿarabe.

I can speak Arabic.

Treating فيني and بقدر as rigid synonyms

❌ قدرت إفتح الباب بس ما فتحته.

Contradictory in the ordinary achieved reading — قدرت إفتح normally says the opening was successfully accomplished.

✅ كان فيني إفتح الباب، بس ما فتحته.

kēn fīne iftaḥ el-bēb, bass ma fataḥto.

I could have opened the door, but I didn't.

Key Takeaways

قدر is a finite ability verb: the b-imperfect expresses current or general capacity, while perfect قدرت often reports managing a particular action. The modal carries person agreement and b-; its lexical complement is bare but agreeing. فيني often foregrounds situational possibility or permission, whereas بقدر can foreground capacity or effort, but ordinary usage overlaps and context decides the framing.
