Ikinyarwanda n’Igikoreya ni indimi zikomoka mu miryango y’indimi itandukanye rwose, kandi zifite imiterere y’imbonezamvugo n’umuco bidahuje na gato. Mu gihe Ikinyarwanda ari ururimi rwo mu muryango w’indimi z’Abantu (Bantu languages) runangwa cyane ku buryo buhamye binyuze mu nteko z’amazina n’inyajwi, Igikoreya cyo ni ururimi rwihafiye (isolated language) cyangwa se ruhuzwa n’indimi za Altai (Altaic languages) rushingiye ku buhuza-majambo (agglutination) n’ikoreshwa ry’utwungo duhamye twomekwa ku mazina. Guhindura inyandiko mu Kinyarwanda uziha mu Gikoreya bisaba ubumenyi bwimbitse butari ubw'amagambo gusa, ahubwo n’ubw’imiterere y’indimi n’imico y’ibihugu byombi. Iyi nyandiko irasesengura mu buryo bwimbitse inzira, inyurabwenge, n’inama z’inzobere zifasha abahinduzi kugera ku buhinduzi bwiza, bwumvikana kandi buhuye n’umuco w’abasomyi b’Abakoreya.
1. Imiterere y'Imbonezamvugo: Umurongo w'Amagambo kuva kuri SVO ujya kuri SOV
Rimwe mu mananiza akomeye mu buhinduzi bw’Ikinyarwanda n’Igikoreya ni iratana ry’umurongo w’amagambo mu nteruro. Ikinyarwanda gikoresha umurongo w’Amagambo w’Ibanze wa SVO (Subject-Verb-Object / Inyito-Inshinga-Icyuzuzo). Urugero: "Yohana yariye umutsima." Yohana (Subject) + yariye (Verb) + umutsima (Object). Mu Gikoreya, umurongo w'amagambo ni SOV (Subject-Object-Verb / Inyito-Icyuzuzo-Inshinga). Urugero rwa mbere mu Gikoreya rwahinduka rutya: "요한이 빵을 먹었다" (Yohana umutsima yariye).
Iri hindurwa ry'umurongo w'amagambo risaba umuhinduzi gusenya burundu interuro y'Ikinyarwanda akazigira mu Gikoreya hakurikijwe imiterere nshya. Iyo umuhinduzi ahindura interuro ndende zifite inyajana n’ingereka, agomba kwitonda cyane kuko inshinga mu Gikoreya ihora iheruka inyuma mu nteruro, kandi ibyafasha byose (nk'ibihe, inyito, n'uburyo bw'inshinga) bikaba ari byo bisoza interuro. Ibi bishobora kugora abahinduzi batamenyereye gutekereza mu buryo bw'Igikoreya, kuko bisaba gutegereza ko interuro yose irangira kugira ngo umenye icyo umuvuzi ashaka kuvuga neza (kuko inshinga ari yo yerekana igikorwa ikaza ku ndunduro).
2. Udutsiko tw'Amazina mu Kinyarwanda n'Utwungo tw'Imbata (Particles) mu Gikoreya
Ikinyarwanda kigira imiterere ikomeye ishingiye ku nteko z’amazina (noun classes), aho amazina agabanyijwe mu matsinda atandukanye (inteko ya 1 kugeza ku ya 20) agenga uburyo ibiungo n’inshinga bikurikirana kandi bikajyana mu nteruro. Urugero, "Umugabo we arakora" (Inteko ya 1) vs "Amagare ye ariko aragenda" (Inteko ya 6). Iri genzura ry'inteko rikoresha uturemajambo tw'imbere (prefixes) kugira ngo interuro igire ubumwe bw’amajambo.
Ku rundi ruhande, Igikoreya nta nteko z’amazina kigira, ahubwo gikoresha utwungo tw’imbata twomekwa ku mazina (postpositional particles) kugira ngo berekane uruhare rw’izina mu nteruro. Utu twungo twerekana umukorezi (이/가 - i/ga), urugero rw’ikiganiro (은/는 - eun/neun), intego y’igikorwa (을/를 - eul/reul), ahantu cyangwa igihe (에/해서 - e/eseo), n'ibindi. Umuhinduzi agomba kumenya neza uko ahindura inshingano z'inteko z'amazina n’utwungo duhuza amagambo mu Kinyarwanda akazishyira mu twungo tw’Igikoreya twiza kandi buhuye n’ururimi rw’umwimerere. Gukoresha nabi utu twungo mu Gikoreya bishobora guhindura rwose icyo interuro isobanura cyangwa bikayigira umugani utumvikana mu matwi y’Abakoreya.
3. Icyubahiro n'Imvugo z'Ikinyabupfura mu Buhinduzi
Imico yombi, y'Abanyarwanda n'Abakoreya, ishyira imbere cyane kubahana n’icyubahiro mu biganiro. Mu Kinyarwanda, icyubahiro cyerekanirwa mu gukoresha ubwinshi bw'icyubahiro (nk’aho ukoresha "Mwe" aho gukoresha "Wowe"), cyangwa mu guhitamo amagambo yihariye ku bantu bakuru cyangwa abayobozi (urugero, "gutaha" mu kinyabupfura bikoreshwa ku bantu bubashywe aho kuvuga "gupfa").
Nyamara, mu Gikoreya, icyubahiro (존댓말 - Jondaetmal) giteye mu buryo bw’imbonezamvugo isobanutse kandi ihambaye cyane kurusha mu Kinyarwanda. Hariho urwego rw’icyubahiro ruhari mu nshinga (verb endings) rushingiye ku kureba niba uwo uvugana na we akuruta mu myaka, mu rwego rw’akazi, cyangwa niba ari umushyitsi. Hariho inshinga zihariye (nk'uko "먹다" - kurya biba "드시다" mu cyubahiro), n’amagambo yihariye y'icyubahiro. Iyo uhindura kuva mu Kinyarwanda uha mu Gikoreya, umuhinduzi agomba kumenya neza imibanire y’abantu kuvugwa mu nyandiko kugira ngo ahitemo urwego rw’icyubahiro rukwiye. Gukoresha imvugo isanzwe (반말 - Banmal) mu gihe hagombaga gukoreshwa imvugo y’icyubahiro bishobora gufatwa n’Abakoreya nko gusuzugura bikomeye cyangwa kutagira umuco.
4. Guhuza Umuco, Imigani n'Imvugo z'Ikigereranyo (Transcreation)
Umuco w'Abanyarwanda urangwa n'amateka akomeye y'ubworozi bw'inka, umuganda, gukunda igihugu, n'imikoranire y'abaturage. Ibi bigaragarira mu mvugo zitandukanye n'imigani. Urugero, imvugo nka "Amata n'ubuki", "Guca akenge", cyangwa "Gukora umuganda" ntizishobora guhindurwa ijambo ku rindi mu Gikoreya kuko nta we wazumva. Umuhinduzi agomba gushaka imvugo z'ikigereranyo mu Gikoreya zifite ubusobanuro busa n'ubw'iz'Ikinyarwanda.
Mu Gikoreya na ho, habamo imvugo zishingiye ku muco wabo, nk'imyizerere y'Abakonfusiye (Confucianism) n'imyifatire ishingiye kuri "Jeong" (정 - urukundo cyangwa umubano w'imbere mu mutima). Iyo uhindura Ikinyarwanda mu Gikoreya, umuhinduzi agomba gukoresha uburyo bwa "Transcreation" (guhindura uhamya icyerekezo cy'umuco). Urugero, "Umuganda" uramutse uhinduwe nka "공동체 봉사 활동" (igikorwa cy'ubushake bw'abaturage) bishobora kumvikana ariko bishobora gukenera ibisobanuro by'inyongezo (footnote) niba ari inyandiko y'amateka, cyangwa bigahuzwa n'indangagaciro z'Abakoreya bita "Dure" (두레 - imikoranire gakondo y'abaturage mu buhinzi).
5. Inama z'Ingenzi ku Bahinduzi b'Ikinyarwanda mu Gikoreya
Kugira ngo ubuhinduzi bwawe bube bwiza kandi busomeke neza nk'inyandiko yanditswe n'umukorezi w'umwimerere, dore inama ugomba gukurikiza:
- Soma witonze inyandiko yose: Mbere yo gutangira guhindura, banza usome inyandiko yose y'Ikinyarwanda kugira ngo ubashe kumva umwuka, intego, n'urwego'imvugo bikwiye gukoreshwa mu Gikoreya.
- Irinde guhindura ijambo ku rindi (Literal Translation): Guhindura ijambo ku rindi hagati y'izi ndimi zombi bitera urujijo kubera gutandukana gukomeye kw'imiterere y'interuro. Centra ku gitekerezo nyamukuru, hanyuma ucyubake mu Gikoreya wifashishije imbonezamvugo yabo.
- Genzura itandukaniro ry'ibihe by'inshinga: Ikinyarwanda gifite ibihe byinshi by'inshinga (urugero: icyahise gikomeza, icyahise cya kure, n'ibindi) mu gihe Igikoreya cyo gifite ibihe bike kandi byoroshye mu buryo bw'inyandiko. Hitamo ibihe bihamye kandi bitanga ubusobanuro bukwiye.
- Koresha inkoranyamagambo z'inzobere: Gura cyangwa wifashishe inkoranyamagambo zizewe kandi ugenzure buri jambo ry'umuco kugira ngo utaryibeshyaho.
- Saba umusomyi w'Umukorezi kubisoma: Nyuma yo guhindura, saba inshuti cyangwa umukozi mugenzi wawe w'Umukorezi (Native Speaker) gusoma inyandiko yawe kugira ngo arebe niba yanditse mu Gikoreya gitemba neza kandi kitarimo amananiza y'ururimi rw'inkomoko.
