Many English nouns ending in -ism correspond directly to French nouns ending in -isme. This is one of the most stable and predictable conversion patterns between English and French. The words are usually shared international terms, often built on Greek or Latin roots that entered both languages through scholarly, political, or scientific use.

Examples such as capitalism → capitalisme and tourism → tourisme show how close the forms remain.

This is a strong pattern, but it is still best treated as a guide rather than a rule. A small number of English -ism words exist in French under different forms or with shifts in meaning.

The basic pattern

The most common pattern is:

• English -ism → French -isme

Examples:

• capitalism → capitalisme
• socialism → socialisme
• tourism → tourisme
• realism → réalisme
• idealism → idéalisme
• nationalism → nationalisme
• pessimism → pessimisme
• optimism → optimisme
• racism → racisme
• feminism → féminisme

Examples:

• Le capitalisme domine l’économie mondiale. “Capitalism dominates the global economy.”
• Le socialisme a différentes formes. “Socialism has different forms.”
• Le tourisme est important dans cette région. “Tourism is important in this region.”
• Le racisme reste un problème social. “Racism remains a social problem.”

Why this pattern is so regular

This is one of the cleanest English to French mappings because:

• Both languages borrow heavily from Greek and Latin abstract nouns
• -ism and -isme are international scholarly endings
• The meaning is usually abstract and conceptual rather than concrete

As a result, the spelling changes very little.

Very close matches

Many pairs are almost identical except for the final vowel.

Examples:

English	French
capitalism	capitalisme
socialism	socialisme
realism	réalisme
idealism	idéalisme
nationalism	nationalisme

Examples:

• Le réalisme politique est important. “Political realism is important.”
• Le tourisme local se développe. “Local tourism is developing.”

Political and social systems

A large group of -ism / -isme words describe ideologies or systems.

Examples:

• communism → communisme
• capitalism → capitalisme
• socialism → socialisme
• liberalism → libéralisme
• conservatism → conservatisme
• fascism → fascisme

Examples:

• Le communisme a marqué le 20e siècle. “Communism marked the 20th century.”

Cultural and behavioural concepts

Another group describes attitudes or ways of thinking.

• realism → réalisme
• cynicism → cynisme
• fatalism → fatalisme

Examples:

• Son pessimisme est exagéré. “His pessimism is exaggerated.”
• Elle montre beaucoup de cynisme. “She shows a lot of cynicism.”

Scientific and technical uses

Many scientific or technical terms also follow the pattern.

• symbolism → symbolisme

Examples:

• Le mécanisme est simple. “The mechanism is simple.”

Cases where meaning shifts slightly

Most -ism / -isme words match well, but meaning can shift in use.

Tourism → tourisme

French tourisme and English tourism are close, but French often uses it in broader economic or institutional contexts.

Examples:

• Le tourisme est une industrie majeure. “Tourism is a major industry.”
• Le tourisme rural se développe. “Rural tourism is developing.”

Realism → réalisme

French réalisme is used in art, politics, and everyday speech.

Examples:

• Le réalisme en peinture. “Realism in painting.”
• Il faut du réalisme dans ce projet. “We need realism in this project.”

Cases where English -ism does NOT become French -isme

Not every English -ism maps neatly.

Examples:

• ageism → discrimination liée à l’âge or âgisme (both exist, but usage varies)
• sexism → sexisme (direct match, but usage is broader in French)
• terrorism → terrorisme (direct match, but meaning is highly context-driven)

Some have direct French forms, others prefer descriptive phrases depending on context.

Related word families

Many -isme nouns are part of larger families:

English noun	English adjective	French noun	French adjective
