rád bych

To build a sentence with this pattern, you must pay attention to double agreement and word order.

1. Double Agreement:
Because rád is an adjective, both it and the main verb must match the subject's gender and number. The auxiliary verb also changes depending on the grammatical person (I, you, he/she/it, etc.):

• 1st person singular (male): rád bych dělal
• 1st person singular (female): ráda bych dělala
• 3rd person singular (neuter): rádo by dělalo (e.g., Dítě by si rádo hrálo)
• 1st person plural (mixed/male): rádi bychom dělali
• 1st person plural (all-female): rády bychom dělaly
• 3rd person plural (neuter): ráda by dělala (e.g., Děvčata by si ráda hrála)

2. The Past Participle & Conditional Logic:
A very common myth is that this pattern takes an infinitive. It does not. Because bych + past participle forms the standard Czech conditional mood (e.g., šel bych = I would go), adding rád simply modifies it (rád bych šel = I would gladly go). Therefore, it strictly requires the past participle (e.g., šel, not jít). You can also attach it directly to a noun without a verb (e.g., Ráda bych kávu - I would like a coffee).

3. Word Order:
The word bych is a clitic that must occupy the strict second position in the clause (second-position clitics). If rád is the first word, bych must immediately follow it. When using reflexive pronouns, bych always precedes se/si in the clitic cluster (e.g., Rád bych si dal kávu or Rád bych se tě na něco zeptal). In questions, either rád or the main verb usually takes the first position to keep bych in the second position (e.g., Rád byste šel? or Šel byste rád?).

4. The Conditional Paradigm and Other Persons:
To use this pattern for all subjects, you need the full set of conditional auxiliaries:

• já (I): bych
• ty (you, singular informal): bys
• on/ona/ono (he/she/it): by
• my (we): bychom
• vy (you, plural/formal): byste
• oni/ony/ona (they): by

For formal singular address, the auxiliary is plural (byste) while the adjective and past participle remain singular (e.g., Rád byste šel? to a man, and Ráda byste šla? to a woman). Important: When the 2nd-person singular bys meets the reflexive pronouns se or si, they must fuse into by ses and by sis (e.g., Rád by sis dal kávu?).

5. Negation and Preferences:

• Negation: To say you would rather not do something, negate the adjective: nerad bych (e.g., Nerad bych tě rušil - I wouldn't want to disturb you).
• Preferences: Use the comparative raději/radši bych (I would prefer to) or superlative nejraději/nejradši bych (I would most like to). Note that these are adverbs and remain invariable regardless of the subject's gender (e.g., a woman still says Raději bych šla). To say 'I would rather not', you must negate the verb, not the adverb (e.g., Raději bych nešel).

Nuance and Register:
While chtěl bych also means 'I would like', rád bych adds a note of warmth and enthusiasm—framing the request as something you would gladly do. Note that in the plural, the standard written form is rádi bychom, though you will frequently hear rádi bysme in casual spoken Czech (standardní bychom vs nespisovné bysme).
