jako by + Conditional

As-if Comparison with Conditional

Level 5

The phrase jako by means "as if" or "as though." It is used to compare a real situation to a hypothetical or unreal one.

How It Works

The pattern jako by is used to describe an actual observation by likening it to a counterfactual scenario. It strictly requires the conditional mood (which in modern Czech is almost exclusively the present conditional).

1. Conjugation and Structure
The word by is not a static particle; it is the conditional auxiliary. It must inflect to match the subject:

  • já: jako bych
  • ty: jako bys
  • on/ona/ono: jako by
  • my: jako bychom
  • vy: jako byste
  • oni/ony/ona: jako by

Because the auxiliary is already present right after jako, you cannot add another auxiliary (like jsem or bych) later in the sentence. Instead, the main verb must take the past participle (l-participle) form, which must agree in gender and number with the subject (e.g., on dělal, jako by spal vs. ona dělala, jako by spala).

Reflexive Verbs in the 2nd Person Singular: When using reflexive verbs in the ty form, the -s from bys shifts to the reflexive pronoun. This results in jako by ses (not jako bys se) and jako by sis (not jako bys si).

Colloquial vs. Standard Forms: In spoken Czech, you will often hear the non-standard form jako bysme instead of jako bychom (see standard bychom versus non-standard bysme). However, be careful in writing: the spelling jako by jsme is a common native-speaker error and is strictly incorrect.

2. Clitic Word Order
The conjunction jako acts as the first-position anchor for the second-position clitics. The conditional auxiliary (bych, bys, by...) is itself the first clitic in this cluster, and any other short pronouns (like se, si, mu, mi, ho, to) must immediately follow it before the main verb. For example: Dělá, jako by se mu to líbilo. (He acts as if he liked it.)

3. Jako by vs. Jakoby
It is crucial to distinguish the two-word jako by from the one-word jakoby:

  • jako by (two words): A conjunction + inflected auxiliary used exclusively to trigger a conditional clause (e.g., Dělá, jako by spal. - He acts as if he were sleeping). Helpful test: If you can replace the phrase with jako kdyby and it still makes sense, it must be written as two words (jako by).
  • jakoby (one word): An uninflected adverb meaning "seemingly," "sort of," or "like." It is used with the indicative mood or non-verbal elements (e.g., Usmál se jakoby nic. - He smiled as if nothing happened). Additionally, the one-word jakoby is heavily overused as a colloquial filler word in spoken Czech, much like the English word "like".

Pronunciation note: In spoken Czech, jako by and jakoby are pronounced exactly the same. This explains why native speakers frequently mix them up in writing and reassures learners who might struggle to hear the difference.

Note: While pairing this pattern with the past conditional (e.g., jako by byl věděl) exists, it is highly archaic. In modern Czech, almost always use the present conditional.

Examples (4)

  1. Mluví, jako by tomu rozuměl.

    He talks as though he understood it.

    Word by Word: He-talks, as if he-understood to-it.

    The auxiliary 'by' is used for the third person, followed by the past participle 'rozuměl'.

  2. Hleděla na něj, jako by ho nepoznávala.

    She stared at him as if she didn't recognize him.

    Word by Word: She-stared at him, as if him she-didn't-recognize.

    Shows the third-person feminine usage. The conditional signals that she actually does know him, but is acting otherwise.

  3. Všichni jsme mlčeli, jako bychom ztratili řeč.

    We were all silent, as if we had lost our ability to speak.

    Word by Word: All we-were-silent, as if-we lost speech.

    Notice how 'bychom' (first-person plural) attaches directly to 'jako'.

  4. Díváš se na mě, jako bys mi nevěřil.

    You are looking at me as if you didn't believe me.

    Word by Word: You-look at me, as if-you to-me didn't-believe.

    The second-person singular auxiliary 'bys' combines with 'jako'.

Common Mistakes

  • Forgetting to inflect the auxiliary 'by' for person and number, or adding an extra auxiliary.

    Mluvím, jako by jsem to věděl.
    Mluvím, jako bych to věděl.

    Because 'as if' is invariable in English, learners often treat 'jako by' as a fixed phrase and incorrectly add 'jsem' or another 'bych' later. The word 'by' must inflect (jako bych, jako bys, jako by, jako bychom, jako byste).

  • Confusing the two-word conjunction 'jako by' with the one-word particle 'jakoby'.

    Tvářil se, jakoby nic nevěděl.
    Tvářil se, jako by nic nevěděl.

    Use the two-word 'jako by' when introducing a conditional clause with a past participle. The one-word 'jakoby' means 'seemingly' or 'sort of' and is used with the indicative mood or non-verbal phrases.

Learn This First

To learn the 'jako by' pattern, a learner must first understand how the Czech conditional mood is formed using the particle 'by' and the past participle. Familiarity with other conjunctions that incorporate the conditional particle (like 'aby') helps in understanding how 'jako by' functions as a single unit that agrees with the subject.
