teprve + Time Expression

Attachment and Usage
Teprve is an invariant focus particle (traditionally classified in dictionaries as an adverb of time) that attaches directly before the specific element it modifies or evaluates (whether that is a time expression, a quantity, or a verb). This can be an adverb (teprve včera), a prepositional phrase (teprve po kontrole), a noun phrase denoting duration or age (teprve dva roky, je mu teprve pět let), or a subordinate time clause (teprve když...). While primarily used with time, the 'progression' logic of teprve also applies to non-time quantities to mean 'only X amount so far'. For example, Máme teprve tři body (We only have three points so far) or Přečetl jsem teprve 20 stran (I have only read 20 pages so far). In everyday spoken Czech, teprve is frequently shortened to teprv (e.g., Je mu teprv pět, My teprv začínáme).

High-Frequency Collocations & Idioms

• teprve teď: only now
• teprve nedávno: only recently
• teprve pak / teprve potom: only then
• teprve až: only when / not until (used to introduce subordinate clauses or conditions, e.g., Uvěřím tomu teprve, až to uvidím.)
• A co teprve...: This highly frequent idiom translates to 'let alone', 'not to mention', or 'talk about...'. It is used to amplify a statement by comparing it to an even more extreme case (e.g., Je to drahé pro mě, a co teprve pro studenta.).
• Teprve + verbs of beginning: When paired with verbs like začínat (to begin), teprve translates to 'only just' (e.g., My teprve začínáme.).
• To se teprve uvidí: That remains to be seen
• To nejlepší teprve přijde: The best is yet to come

Crucial Distinctions

• The 'Not Until' Translation Trap: English expresses this concept with a negative verb (e.g., 'He won't arrive until tomorrow'). Czech, however, uses a positive verb with teprve (or až). You must drop the negation: Přijde teprve zítra (literally: 'He will arrive only tomorrow'). Translating the English negative literally (e.g., Nepřijde dokud zítra) is highly ungrammatical.
• Teprve vs. Už: In Czech pedagogy, teprve is often taught as the direct semantic opposite of už (already). While už indicates that a threshold has been reached sooner than expected (Jsou už dvě hodiny - It is already two o'clock), teprve indicates it has not progressed as far as expected (Jsou teprve dvě hodiny - It is only two o'clock).
• Teprve vs. Jen: Jen restricts quantity; teprve evaluates time progression. 'It is only 2 o'clock' is Jsou teprve dvě hodiny. However, jen can be used with time when referring to a restricted allowance or quantity of time, such as Mám na to jen dvě hodiny (I only have two hours for it). This contrast between static limitation and progression also applies to non-time quantities: Mám jenom 100 Kč (I only have 100 CZK — that is all I have, static fact) vs. Mám teprve 100 Kč (I only have 100 CZK so far — I am still earning/collecting, progression).
• Teprve vs. Až: Až also translates to 'not until' for points in time. When used with points in time, teprve emphasizes how recent something is, while až emphasizes how late it is. For example, Přišel teprve včera (He only arrived yesterday - emphasizes how recent it is) vs. Přišel až včera (He didn't arrive until yesterday - emphasizes how late it is). Furthermore, až cannot be used for durations to mean 'only so far'. Učím se to teprve rok is correct; using až here would incorrectly mean 'up to a year'.
• Teprve vs. Nejprve: Despite phonetic similarities, nejprve means 'first of all' in a sequence, whereas teprve means 'not until'.

Widespread Myths Debunked

• The Past vs. Future Myth: Some simplified materials claim teprve is strictly for past events and až is strictly for future events. This is inaccurate. Both can be used in the future, but with a nuanced difference: až is the default, neutral 'not until' for future events, whereas teprve adds a heavy, exclusive focus meaning 'only then and absolutely no sooner' (e.g., Soud rozhodne teprve v červnu). Furthermore, až is common in the past. The real distinction lies in teprve's ability to evaluate elapsed duration and its stronger focus on defied expectation.
• The Teprve Až Redundancy: Traditional prescriptivists flag the combination teprve až (e.g., teprve až zítra) as redundant. While it technically is a pleonasm, corpus data confirms it is widely and naturally used by native speakers to add double emphasis ('not until absolutely'). It is common in spoken Czech and occasionally appears even in formal writing.
