仮定形: meaning, usage and examples
仮定形 means: Verb Conditional-form.
How to form it
Group 1: -u -> -eba (書く -> 書けば) / Group 2: -る -> -れば (食べる -> 食べれば) / する -> すれば / 来る -> 来れば (くれば); negative: ない -> なければ (書かなければ)
Examples
飲めば、食べれば、すれば、来れば
[Conditional-form] of drink, eat, do, come
春が来れば、桜が咲きます。
When spring comes, the cherry blossoms will bloom.
毎日練習すれば、上手になりますよ。
If you practice every day, you will get better.
この薬を飲めば、すぐ治ります。
If you take this medicine, you will get better soon.
急がなければ、電車に遅れます。
If we don't hurry, we'll be late for the train.
When to use it
The conditional ば form means "if" and links a condition to its result: 練習すれば上手になります (If you practice, you will improve). It is often used for general truths, advice and what you need to do to get a result. The negative なければ means "if you don't" and appears in なければならない (must).
Nuance
ば focuses on the condition: "only if this happens, that follows." When the second half is a request, invitation or intention (ください, ましょう, つもり), ば is usually avoided if the first half is an action verb; use たら instead. い-adjectives use -ければ (高ければ) and nouns or な-adjectives use なら.
Compare
ば (general condition): 押せば開きます. たら (after it happens, also for one-time events and requests): 駅に着いたら電話してください. と (always, automatic result): 押すと開きます. なら (if that is the case, responding to a topic): 京都に行くなら、お寺を見てください.
Tip: The form is easy: change the last -u sound to -e and add ば (飲む -> 飲めば). For requests after "if," choose たら instead.
