言うに言えない・
These paired patterns present an action as wanted, intended, or emotionally pressing, then show that it is blocked. The speaker would do it, but cannot because of hesitation, circumstances, or a missing condition.
How the pairing works
The same action appears twice. The first half brings that action strongly to mind; the second says that carrying it out is impossible. This is more expressive than simply using a negative potential verb because it highlights the tension between wanting or needing to act and being unable to do so.
Established pairings
The dictionary-form pattern is especially natural in familiar combinations involving emotional or interpersonal hesitation. Do not assume that every verb can be inserted freely.
An obstacle blocks the intended action
The volitional pattern is more productive. It commonly appears when a concrete obstacle or missing condition makes the intended action impossible.
The obstacle can take different forms
Emotional hesitation is common with the first pattern, while visible situational obstacles are common with the volitional pattern. This is a useful tendency, not a strict division: either pattern can involve emotional, interpersonal, physical, or practical barriers when the wording and context are natural.
Other ways to express impossibility
ようがない says that there is no possible method. わけにはいかない usually presents an action as unacceptable because of social, moral, or practical responsibility. どうにも～ない broadly describes something as unmanageable. The present patterns differ by repeating one salient action and setting the wish or intention to perform it directly against the inability to do so.
