قول ِمحال:(Paradox)
"ایسا تضادی بیان جو مسلمہ تصور کے برعکس ہو، پیراڈاکس کہلاتا ہے۔"
لیکن قولِ محال محض تضاد نہیں بلکہ قولِ محال جہاں شروع ہوا ہے، وہاں تضاد ختم ہونے لگتا ہے۔ تضاد تو ایک عمومی حقیقت ہے جس کے فنی بیان میں دلکشی تو ہے، صنعت کاری کا جمالِ فریب نہیں۔ اسے اتحادِ ضدین بھی کہہ سکتے ہیں۔
"پیراڈاکس’’ انیسویں صدی کی جدید صنعتِ بیان ہے جو ایک نوع کی ذہنی ورزش ہے۔نثر و نظم میں قولِ محال پیدا کرنا اور اس سے حِظ یاب ہونا، ترقی یافتہ ذہن کا کام ہے۔یہ انگریزی ادب سے ہمارے ہاں آیا۔انگریزی ادب میں آسکر وائلڈ، چسٹرٹن اور برنارڈ شا اس کے نقیب ہیں۔اردو شاعری میں قولِ محال کی مثالیں دیکھیے:
ہم نے جس شخص کو توقیرِ شناسائی دی
اس نے خوش ہوکے ہمیں عزتِ رسوائی دی
(دوسرے مصرعہ میں قولِ محال "عزتِ رسوائی"ہے)
جہلِ خرد نے دن یہ دکھائے!
گھٹ گئے انساں، بڑھ گئے سائے
(پہلے مصرعہ میں قولِ محال "جہلِ خرد’’ ہے)
(پروفیسر انور جمال کی تصنیف "ادبی اصطلاحات’’ مطبوعہ نیشنل بْک فاؤنڈیشن، اشاعتِ چہارم، مارچ 2017ئ￿ ، صفحہ نمبر 144 سے انتخاب)
ابہام:(Ambiguity)
ابہام ایک انگریزی اصطلاح ہے جسے اردو ادب میں بھی استعمال کیا جاتا ہے۔ابہام کی صورت حال اس وقت رونما ہوتی ہے جب کسی لفظ، محاورے، جملے، اشارے وغیرہ کی ایسی ترسیل کی جائے کہ اس سے ایک کی بجائے کئی معانی اور مطالب ممکن ہوں۔ ابہام کا ایک عام پہلو عدم تعین ہے۔ یہ ہر خیال یا بیان کا خاصہ ہے جس کے ارادی معانی قطعی طور کسی اصول یا طریق? کار کی روشنی میں سلجھائے نہیں جا سکتے جس میں مقررہ اقدامات شامل ہوں۔
ابہام کی مثالیں:
کئی الفاظ جن کا عام طور سے استعمال کیا جاتا ہے، مختلف لوگوں کے لیے مختلف معانی کے حامل ہوتے ہیں۔ مثلًا لمبا یا...

ابتكارات العلامة الزمخشري في علم المعاني خلال أسلوب السؤال والجواب في تفسيره الكشاف

Semantic (علم المعاني) is the most interesting branch of Rhetoric. Al-Zamakhsharī has discussed its categories in his introduction to “Al- Kashshᾱf”. He has elaborated the terminology of Semantics but he did not arrange it separately in chapters and did not apply this division in Al- Kashshᾱf as well. The Great Scholar of Rhetoric Al-Sakkᾱkī has categorized semantics in the form of three terminologies: the Knowledge of Semantic, (علم المعاني) the Knowledge of Eloquence, (علم البيان) the figures of speech (علم البديع). Al-Zamakhsharī was very influenced by The Great Scholar and Literary Theorist Abd-ul-Qᾱhir Al-Jurjᾱnī since he implemented whatever Abd-ul-Qᾱhir Al-Jurjᾱnī pointed out in his book “Arguments of Miracles” and “Mysteries of Rhetoric” whilst analyzing Qur’ᾱnic Verses in his exegesis “Al-Kashshᾱf” on Rhetorical basis, though he mentioned in his exegesis all foremost and supreme aspects of Rhetoric which were not referred to by any former scholars. In this article I have widely discussed the unique and distinguished rhetorical topics, highlighted by Al-Zamakhsharī in his exegesis Al-Kashshᾱf, for instance; he semantically analyzed letters and verbs in the Holy Qur’ᾱn, particularly propositional and non-propositional verbs. At the end of this article I tried my best to conclude the topic with better sequences. 

Effect of Berberis Mediated Biosynthesized Silver Nanoparticles on Growth and Yield Attributes of Pisum Sativum L.

The present study was aimed to evaluate the effect of biologically synthesized silver nanoparticles using Berberry (Berberis lycium Royle) on growth and yield attributes of pea (Pisum sativum L.). Moreover, Taxonomy and distribution of genus Berberis from Azad Jammu and Kashmir (AJK), Pakistan were also recorded. A total of 9 species of Berberis such as B. brandisiana, B. chitria, B. glaucocarpa, B. kashmirana, B. lycium, B. parkeriana, B. royleana, B. sterwartiana and B. ulicina were identified. These species were distributed from sub-tropical to sub-alpine zones of the state of AJK, Pakistan. It was found that B. lycium distributed in maximum studied sites and further selected for the synthesis of silver nanoparticles. Confirmation of silver nanoparticles synthesis was made on colour change when aqueous bark extract treated with AgNO3 which was further established with uv-visible spectroscopy. Structural and morphological characterization of synthesized nanoparticles was made with scanning electron microscopy, energy dispersive x-ray and x-ray diffraction analysis. Atomic absorption spectrometry (AAS) was used to determine the rate at which silver ions reduced to AgNPs. It was found that biosynthesized silver nanoparticles were pre dominantly spherical, nano in size and crystalline in nature. The morphology of silver nanoparticles was affected by extract and AgNO3 concentrations, temperature and pH. Fourier transform infrared and quantitative screening of bio-molecules confirmed the involvement of alkaloids, flavonoids and reducing sugars as reducing and capping agents of silver nanoparticles. Then these biosynthesized silver nanoparticles were applied on P. sativum to find out their effect on growth and yield of pea. For this, a field experiment was conducted in split-split plot xvi fashion following RCBD. Three varieties of pea (Climax, PF-400 and Meteor) were treated with four concentrations of silver nanoparticles (0, 30, 60 and 90 ppm) by means of three modes of application (Seed treatment, foliar spray, seed treatment plus foliar spray). The results were found to be significant with respect to root length, shoot length, chlorophyll contents, seeds pod-1, pods plant-1, 100 seeds weight, biological yield, green pod yield, seed protein and carbohydrate contents. Among the concentrations of silver nanoparticles, 60 ppm produced maximum results applied via seed treatment plus foliar spray. Present findings suggest that silver nanoparticles enhanced the growth and yield of pea at a concentration of 60 ppm.
