TL;DR 🦄
  • 🤔 -(으)ㄹ까 하다 [-(eu)l-kka ha-da] means to be thinking of doing / considering doing something.
  • 🧩 Vowel stem + ㄹ까 해요, consonant stem + 을까 해요: 예약하다 → 예약할까 해요, 읽다 → 읽을까 해요.
  • 🪶 It sounds tentative: softer than -(으)려고 하다 (planning to) and much less final than -기로 하다 (decided to).

🌈 The Big Picture

-(으)ㄹ까 하다 is for a tentative plan: you are leaning toward doing something, but it is not fully decided yet. It feels like “I’m thinking of…” or “I might…” 🤔
Use it when the speaker is quietly weighing an action:
  • 오늘은 병원에 전화할까 해요. [o-neu-reun byeong-wo-ne jeon-hwa-hal-kka hae-yo] (I’m thinking of calling the hospital today.) 🏥
  • 점심은 밖에서 먹을까 해요. [jeom-si-meun ba-kke-seo meo-geul-kka hae-yo] (I’m thinking of eating lunch outside.) 🍱
It is different from a clear plan or decision:
  • 전화하려고 해요. [jeon-hwa-ha-ryeo-go hae-yo] (I’m planning to call.) 📞
  • 전화하기로 했어요. [jeon-hwa-ha-gi-ro hae-sseo-yo] (I decided/agreed to call.) ✅
  • 전화할까 해요. [jeon-hwa-hal-kka hae-yo] (I’m thinking of calling.) 🤔

🎨 The Core Tentative-Plan Family

Vowel stem + ㄹ까 해요

  • 살다 [sal-da] (to live) → 살까 해요 [sal-kka hae-yo] (I’m thinking of living)
  • 열다 [yeol-da] (to open) → 열까 해요 [yeol-kka hae-yo] (I’m thinking of opening)
  • 팔다 [pal-da] (to sell) → 팔까 해요 [pal-kka hae-yo] (I’m thinking of selling)
Negative tentative plan
  • 안 전화할까 해요 [an jeon-hwa-hal-kka hae-yo] (I’m thinking of not calling)
  • 마시지 말까 해요 [ma-si-ji mal-kka hae-yo] (I’m thinking of not drinking it)
  • 사지 말까 해요 [sa-ji mal-kka hae-yo] (I’m thinking of not buying it)
Useful real-life words in this lesson:
  • 오늘 [o-neul] = today, 내일 [nae-il] = tomorrow, 이번 주말 [i-beon ju-mal] = this weekend, 잠깐 [jam-kkan] = briefly/for a moment
  • 병원 [byeong-won] = hospital, 카페 [ka-pe] = cafe, [bak] = outside, [jip] = home/house, [bang] = room
  • 예약 [ye-yak] = reservation, 영수증 [yeong-su-jeung] = receipt, 메시지 [me-si-ji] = message, 사진 [sa-jin] = photo, [chaek] = book

🛠️ How They Work in a Sentence

  • 예약 시간을 바꿀까 해요. [ye-yak si-ga-neul ba-kkul-kka hae-yo] (I’m thinking of changing the reservation time.) 🕒
    • 예약 시간 = reservation time, 바꾸다 = to change/switch.
  • 이 메시지를 내일 보낼까 해요. [i me-si-ji-reul nae-il bo-nael-kka hae-yo] (I’m thinking of sending this message tomorrow.) 💬
    • = this, 메시지 = message, 보내다 = to send.
  • 오늘은 커피를 마시지 말까 해요. [o-neu-reun keo-pi-reul ma-si-ji mal-kka hae-yo] (I’m thinking of not drinking coffee today.) ☕
    • 커피 = coffee, 마시지 말다 = to not drink / refrain from drinking.

🧩 General Formation Rule

Vowel stem
  • Remove → add ㄹ까 해요
    • 전화하다 → 전화할까 해요
    • 예약하다 → 예약할까 해요
    • 쉬다 → 쉴까 해요
    • 보내다 → 보낼까 해요
Consonant stem
  • Remove → add 을까 해요
    • 읽다 → 읽을까 해요
    • 먹다 → 먹을까 해요
    • 찾다 → 찾을까 해요
    • 앉다 → 앉을까 해요
ㄹ stem
  • Keep → add 까 해요
    • 만들다 → 만들까 해요
    • 살다 → 살까 해요
    • 열다 → 열까 해요
Usage note
  • -(으)ㄹ까 해요 is most natural when talking about your own tentative intention.
  • For someone else’s tentative intention, Korean often uses reported speech later, like “they said they’re thinking of…”; keep this lesson focused on the speaker’s own thought.
  • Do not confuse -(으)ㄹ까 해요 (I’m thinking of doing) with -(으)ㄹ까요? (Shall we / should I?) or -(으)ㄹ까 봐 (because I’m worried that…).

📚 Cross-check note

The -(으)ㄹ까 ending and related ㄹ까/을까 forms were cross-checked against korean.go.kr. The lesson keeps the usage beginner-focused as a tentative “thinking of doing” expression. ✅

🪞 Synonym Alert

  • -(으)ㄹ까 하다 [-(eu)l-kka ha-da] → thinking of doing; tentative and undecided 🤔
  • -(으)려고 하다 [-(eu)ryeo-go ha-da] → planning/intending to do; firmer plan 🗓️
  • -기로 하다 [-gi-ro ha-da] → decide/agree to do; decision already made ✅
  • -고 싶다 [-go sip-da] → want to do; desire, not necessarily a plan 💭

⚠️ Pitfalls to Dodge

  • 먹ㄹ까 해요 → ✅ 먹을까 해요 (Consonant stem needs 을까.) 🍱
  • 만들을까 해요 → ✅ 만들까 해요 ( stem keeps ; do not add .) 🛠️
  • 전화할까요 해요 → ✅ 전화할까 해요 (Do not mix question 까요? with 해요.) 📞
  • 예약할까 했어요 for a current thought → ✅ 예약할까 해요 (Use present 해요 for “I’m thinking of… now.”) 📅
  • ❌ Using -(으)ㄹ까 해요 for a firm decision → ✅ use -기로 했어요 when the choice is already settled. ✅

Tiny hesitation, real grammar: 전화할까 해요 lets you sound thoughtful without overcommitting. Korean planner goblin approves. 🤔📋

Tip 💡 Pitfall patrol: ㄹ까 해요 is not ㄹ까요 해요, and tentative is not final.
 
🎉 Tentative-plan grammar unlocked. Now you can say “I’m thinking of…” without pretending the decision is final: 전화할까 해요, 읽을까 해요, 만들까 해요. Soft plans, strong Korean. 🤔✨
