dokonce / ba i + Focused Phrase

In Czech, i and ani function as the primary scalar additive focus particles, meaning 'even' and 'not even'. To intensify this meaning and explicitly indicate that the focused item is the least likely or most extreme addition to a set of expectations, Czech uses the intensifiers dokonce and ba.

1. Attachment and Word Order
These particles attach directly before the focused constituent, which can be a noun, pronoun, adjective, verb, or entire clause. You simply attach the particle to the front of the constituent and rely on Sentence-final focus or natural word order. Note that if the focused constituent is a verb or a whole clause, Czech Second-position clitics (like se, si, ho, mu) will often split the intensifier and the primary particle (e.g., Dokonce se i usmál.). You can also use dokonce entirely on its own (e.g., Dokonce plakal.).

2. Negative Concord
If the clause is negative, Czech requires negative concord. The primary particle i must change to ani. Therefore, dokonce i becomes dokonce ani, and ba i becomes ba ani (not even). However, you can also simply drop the i/ani and let dokonce stand alone in a negative sentence (e.g., Dokonce nepřišel.).

3. Register Differences & Combinations

• Dokonce (i): Highly frequent, neutral, and ubiquitous in everyday spoken and written Czech.
• Ba (i): Formal, literary, and somewhat archaic. It translates closer to "nay, even" or "and what's more." Using it in casual conversation sounds highly unnatural, though you will frequently encounter it in fixed phrases like ba co víc (what's more) and ba naopak (on the contrary). Additionally, ba can function as a standalone colloquial or archaic interjection of agreement meaning "yes" or "indeed" (e.g., Ba, máš pravdu.).
• Ba dokonce (i): For extra emphasis, these two particles are frequently combined. Like the others, this combination can take i in positive sentences (e.g., Ba dokonce i plakal.) and ani in negative ones (Ba dokonce ani nepozdravil.).

4. Punctuation Rules
When modifying a single constituent, no comma is used, regardless of whether it is at the start of a sentence (Dokonce i Petr přišel.) or mid-sentence (Je to těžké dokonce i pro experty.). However, a comma is required when dokonce introduces a gradational addition to a list or connects clauses (Pršelo, dokonce i sněžilo.). Crucially, this gradational relationship overrides the standard "no comma before a" rule: when using the conjunction a immediately adjacent to these particles (, a dokonce i or , a ba i), a preceding comma is mandatory. If dokonce is separated from a deeper in the clause, the comma becomes optional.

5. Common Confusions
Do not confuse the focus particle dokonce (one word) with the prepositional phrase do konce (two words, meaning "until the end"). Additionally, while i alone can mean "even," it is often just a coordinating conjunction ("and/also"). Adding dokonce explicitly forces the surprising, scalar interpretation.
