Sense: adjective/2
All four words can refer to something not visible on the surface, but each has a distinct scope. Inner is the most versatile and common — it works for both physical layers ("inner wall") and mental states ("inner peace"), and is the everyday word for describing thoughts or feelings not shown to others. Internal is more formal and often used in medical, organisational, or technical contexts ("internal bleeding", "internal review"), suggesting a structured inside rather than a personal one. Private emphasises deliberate concealment — a private thought is one you choose not to share, while an inward thought might simply be unexpressed by nature. Inward is the least common of the four and carries a slightly literary or introspective tone, often suggesting a spiritual or contemplative quality. For example: "She kept her inner doubts hidden" (natural and common); "The internal report was never released" (organisational); "His private journals revealed a sensitive side" (deliberately hidden); "Her inward struggle lasted for years" (introspective, literary).

Etymology
Inward comes from Old English inweard, a combination of in (meaning 'inside') and -weard (a suffix meaning 'toward'). The word has carried both physical and mental senses since its earliest recorded use. The noun sense for organs (plural inwards) developed later, from the idea of 'the inner parts.' The financial sense emerged in the 20th century with the growth of international economics.
