Questions & Answers about Gdy będziemy zdrowi, ćwiczyć będzie łatwiej i szybciej.

Why is gdy used here instead of kiedy or jeśli?

• gdy generally means “when” for events expected or certain to happen.
• kiedy can also mean “when,” but is more neutral and often used in questions or to refer to general points in time.
• jeśli means “if,” implying a hypothetical or uncertain condition.
  In our sentence the speaker treats being healthy as a real/future certainty, so gdy is the best choice.

Could we use the present tense jesteśmy instead of będziemy in the subordinate clause?

• Polish sometimes uses the present tense for near future in main clauses (e.g. Jutro przyjeżdżam = “I’m arriving tomorrow”).
• However, after conjunctions like gdy that refer to a future condition, the future tense is preferred to avoid confusion.
• Saying Gdy jesteśmy zdrowi… sounds like a general present-fact (“When we are healthy [in general]…”), not a future scenario.

Why is the predicate adjective zdrowi in that form?

• zdrowi is the nominative plural form of zdrowy, agreeing with będziemy (“we will be”).
• The group is assumed to include at least one male (masculine personal plural).
• If it were an all-female group, you’d say zdrowe (Gdy będziemy zdrowe…).

What grammatical role does the infinitive ćwiczyć play? Why not use ćwiczymy?

• The infinitive ćwiczyć functions as the subject of the main clause: “Exercising will be easier and faster.”
• In Polish you often use an infinitive to express impersonal statements about actions.
• ćwiczymy (“we exercise”) would make it a personal statement (“we exercise will be easier?”), which is ungrammatical here.

Why is the word order ćwiczyć będzie łatwiej i szybciej instead of będzie łatwiej i szybciej ćwiczyć?

• Polish word order is flexible and conveys emphasis.
• Placing ćwiczyć first highlights the action itself.
• You could also say:
  • Będzie łatwiej i szybciej ćwiczyć.
  • Łatwiej i szybciej będzie ćwiczyć.
  The meaning stays the same; only the focus shifts slightly.

Can we include the dative pronoun nam (“to us”)? Where would it go?

Yes. A more explicit version is:
• Gdy będziemy zdrowi, będzie nam łatwiej i szybciej ćwiczyć.
You can position nam before the adjectival predicates or before the infinitive:
• …ćwiczyć będzie nam łatwiej i szybciej.

How are łatwiej and szybciej formed? Are they comparatives?

• Both are comparative adverbs:
  • łatwo → łatwiej (“easily” → “more easily”/“easier”)
  • szybko → szybciej (“quickly” → “more quickly”/“faster”)
• In Polish, comparatives often end in -ej or -iej, with some irregular stems (like szybko → szybciej).

Is there an implied subject for będzie like the English “it”?

• English uses a dummy “it” in “It will be easier…”.
• Polish does not need such a placeholder.
• The infinitive ćwiczyć acts as the grammatical subject, so no extra pronoun is required.
