If the United States had colonized Malaysia in the 20th century and decided to rename Kuala Lumpur, while also wanting to emphasize its epithet "Garden City of Light," the U.S. might have chosen a name that resonates with American naming conventions and reflects the symbolism behind the epithet. Considering this, the capital might be renamed something like: 1. Lumina Garden 2. Lightshine City 3. Illumina Park 4. Radiant Garden City 5. Beacon Garden Metropolis These fictional names combine elements of light or illumination with references to gardens or greenery, which would be fitting for the capital nicknamed "Garden City of Light." However, it is important to note that this scenario is entirely speculative and in reality, Kuala Lumpur has remained the capital of Malaysia, a nation with its own rich and independent history that has not been colonized by the United States.

In Greek, the word "phos" (phos) means "light," and "kepos" (kepos) means "garden." To create a compound Greek name similar to "Philadelphia," which combines "philos" (philos, "love") and "adelphos" (adelphos, "brother"), we can merge the words for light and garden. A possible Greek name for "Illuminated Gardens" might be "Phosterikepos" (Phosterikepos), which combines "phoster" (phoster, a poetic and less common word for "light-bringer" or "illuminator") with "kepos" (kepos, "garden"). This name would reflect the idea of a place that is a garden illuminated by light. This new name, Phosterikepos (Phosterikepos), although not conventional in Modern Greek, could resonate with the classical compound place names like "Philadelphia." It's vital to acknowledge, however, that such a name would be a neologism created for a hypothetical scenario and is not an actual Greek word or place name.

To create a Greek-style name for "Illuminated Gardens" that ends in "ia," we can combine a version of the Greek word for light with a suffix that indicates a place or land, which is commonly "-ia" in Greek-derived place names. The Greek word for light is "phos" (phos), and in compound words it often takes the form "photo-" (photo-). Here's a crafted name: **Photokipia** (Photokepia) This name merges "photo-" (photo-, from "phos," meaning "light") and a variation of "kepos" (kepos, meaning "garden"), adapted to "-kipia" to reflect a land or place of gardens bathed in light. This formation echoes other place names ending in "-ia," like "Columbia" or "Bohemia." Again, "Photokipia" would not be a standard Modern Greek term and is a modern construct to fit the hypothetical scenario. Nonetheless, it carries the intended meaning of a land or city characterized by illuminated gardens.

Certainly, a more harmonious Greek-inspired name ending in "ia" for "Illuminated Gardens" could be: **Photeinia** (Photeinia) In this hypothetical name, "Photeinia" combines "photeinos" (photeinos), meaning "bright" or "full of light," with the Greek place-name suffix "-ia," suggesting a place, land, or domain. The name conveys the concept of a place characterized by brightness and light, reminiscent of illuminated gardens. It's worth noting that this name has a pleasant, euphonic quality in English and could be easily pronounced by English speakers, which might be a consideration if a U.S.-influenced name were to be chosen.
